Check your coin for valuable errors and varieties
Values shown are typical retail estimates as of 2026-01.
The 2023 Kennedy half dollar is a recent issue; market values are still establishing and may fluctuate.
Error coin values vary significantly based on grade, eye appeal, and current market conditions.
Professional authentication (PCGS/NGC) is recommended for high-value varieties, especially the VDDO-001 and VDDR-001.
Machine Doubling (flat, shelf-like projections) is NOT a valuable error — it is the most common misidentification on 2023 Kennedy halves.
Die Deterioration Doubling (shadowy halos near the rim) is NOT a valuable variety — it is normal die wear from high-volume production.
Weight verification with a digital scale (0.01g accuracy) is essential for authenticating Missing Clad Layer errors and distinguishing clad from silver proofs.
The 2023 Kennedy half dollar returned to full bank circulation for the first time since the early 1980s.
In 2023, the U.S. Mint struck more than 44 million Kennedy half dollars for actual bank circulation — the largest run since the early 1980s. That production boom put fresh coins into bank rolls nationwide and reopened a real treasure hunt: the high-speed presses needed to meet Federal Reserve orders inevitably produce die varieties and planchet errors that sharp-eyed collectors can pull from change and coin boxes.
Most of those coins are worth exactly 50 cents. But one confirmed doubled die variety sells for $10–$20 raw, a scarce Denver reverse variety has asked $100–$120+, and major planchet errors can hit $100–$300. This guide covers every confirmed 2023 Kennedy half dollar error, explains what it's worth, and — just as importantly — shows you how to tell a real find from the worthless look-alikes that dominate coin-hunting forums.

2023 Kennedy Half Dollar: Specifications & Mintage
Before searching for errors, you need to know the baseline specs — they are essential for authenticating planchet errors and distinguishing clad coins from silver proofs.
| Specification | Clad (P & D Mint) | Silver Proof (S Mint) |
|---|---|---|
| Composition | 91.67% Cu, 8.33% Ni — outer layers 75% Cu / 25% Ni; pure copper core | 99.9% Silver |
| Weight | 11.34 g | 12.50 g |
| Diameter | 30.61 mm | |
| Edge | Reeded — visible copper stripe | Reeded — solid white, no copper layer |
| Mint Facility | Type | Mintage (Approx.) |
|---|---|---|
| Philadelphia (P) | Circulation / Uncirculated | 17,010,000 |
| Denver (D) | Circulation / Uncirculated | 27,800,000 |
| San Francisco (S) | Clad Proof | ~331,314 |
| San Francisco (S) | Silver Proof | TBD (Limited) |
Clad edge (left) shows a copper stripe between nickel layers. Silver proof edge (right) is solid white with no copper.
2023-S Clad Proof Values
The 2023-S clad proof was struck for inclusion in the annual Proof Set at approximately 331,314 coins. In original Proof Set packaging, examples typically trade for $5–$15. Grade drives value at the top end — PF69 Deep Cameo and PF70 command the highest prices; lower grades often sell near face value at set break-out.
2023-S Silver Proof Values
The 2023-S Silver Proof is struck in 99.9% fine silver (12.50 g) and was included in the Silver Proof Set and the Limited Edition Silver Proof Set. These coins track silver spot prices and collector demand, typically trading for $20–$40+. Confirm silver identity by checking the edge (solid white, no copper stripe) and weighing (12.50 g vs. the clad's 11.34 g).
Limited Edition Silver Proof Set (LESPS)
The 2023 Limited Edition Silver Proof Set contained eight 99.9% silver coins, including the Kennedy half dollar, along with the American Eagle Silver Proof and five American Women Quarters. Production was capped at 50,000 units with a household order limit. Silver Kennedy halves from this set carry a modest premium over standard Silver Proof Set examples due to the lower overall production figure.

2023 Kennedy Half Dollar Quick Checks: Do You Have Something Valuable?
Run through these checks in order. You need a 10x loupe (a small magnifying glass) for the doubling checks and a digital scale accurate to 0.01 g for the weight checks. Both tools are inexpensive and essential for this coin.
Check 1: VDDO-001 Doubled Die Obverse — P mint only
The motto IN GOD WE TRUST — especially the letters I and N in "IN" and G and O in "GOD." Also examine LIB in LIBERTY and the P mintmark below Kennedy's neck on the obverse (front).
A distinct spread toward the east/southeast on motto letters. Notching on letter corners and serifs — letters appear thicker, not thinner. Split upper serifs on the L and I of LIBERTY. A "fat" or notched P mintmark.
Machine Doubling: flat, shelf-like projections that make letters look thinner and step into the device — extremely common on 2023 halves. Die Deterioration: indistinct shadowy halos near the rim without crisp notching. Both are worth face value only.
Check 2: VDDR-001 Doubled Die Reverse — D mint only
The reverse (back) design — the eagle's feathers, arrows, olive branch, and the lettering UNITED STATES OF AMERICA and HALF DOLLAR.
Rounded, clean separation of design elements with visible notching on feathers or letter corners. The doubling should add to the design — elements appear thicker or wider, not flattened or stepped.
Machine Doubling (flat shelf) and Die Deterioration (indistinct shadowy halo near the rim) are both extremely common on 2023-D coins. Denver's 27.8 million coin run pushed dies past their useful life, generating a flood of non-valuable die-wear artifacts. Neither has any premium.
Check 3: Missing Clad Layer — P or D mint
One entire side of the coin. A missing clad layer produces a fully copper-red surface on that side instead of the normal silver-white nickel appearance.
Copper-red side AND coin weighs 9.5–9.8 g — approximately 15% less than the standard 11.34 g. Both conditions must be present. Weight is non-negotiable for authentication.
Acid-dipped, copper-plated, or environmentally damaged coins look copper-red but weigh the full 11.34 g or more. These are post-mint alterations ("science experiment" coins) with no numismatic value. Always weigh before getting excited.
Trap Check: Machine Doubling — NOT Valuable
The date, Kennedy's profile, and lettering on both sides. Extremely common on all 2023 Kennedy halves due to high-speed Federal Reserve order production.
Flat, shelf-like step-down projections extending from one side of a letter or device element. Letters look thinner and stepped — like a shadow cut into them — not wider or thicker.
True doubled dies (like the VDDO-001) show rounded, notched secondary images that add to the design — letters look wider. Machine Doubling shows flat shelves that remove from the design — letters look stepped and narrower. See the Traps section →
Trap Check: Die Deterioration Doubling — NOT Valuable (especially D mint)
The date and letters near the rim on later die states — primarily on 2023-D coins. Denver's massive 27.8 million coin run pushed dies well past their prime, making this widespread.
An indistinct, shadowy halo or ghosting around design elements that radiates outward toward the rim. It lacks any crisp edge or defined secondary image.
True doubled dies have crisp notching and clean, rounded separation. Die Deterioration Doubling is blurry, undefined, and directional toward the rim. It is normal die wear — not a collectible variety. See the Traps section →

⚠️ Note on Auction Records
The 2023 Kennedy half dollar is a recent issue. Certified population data and auction records for 2023-specific varieties are still limited as of early 2026. Values shown reflect asking prices and raw sales observed in the market. A precedent for high-grade error premiums exists in the Kennedy series — a 1973-S Kennedy error realized over $5,000 at auction — but 2023-dated records are not yet established for the varieties listed above.
2023 Kennedy Half Dollar Errors Worth Real Money: Detailed Guides
Philadelphia (P) Mint Errors
Despite Philadelphia's lower mintage (17,010,000 vs. Denver's 27,800,000), the P mint produced the primary confirmed doubled die of the 2023 issue. The VDDO-001 is cataloged by Variety Vista and CONECA and is the top target for Philadelphia roll hunters searching bank boxes and Mint-direct bags.
2023-P VDDO-001 Doubled Die Obverse (CONECA 1-O-VIII)
Normal 2023-P (left) vs. VDDO-001 (right) — note the eastward notched spread on I, N, G, O in "IN GOD."
Origin & Background
The VDDO-001 was cataloged by James Wiles for Variety Vista and is listed in the CONECA (Combined Organizations of Numismatic Error Collectors of America) files as 1-O-VIII. The Roman numeral "VIII" designates Class VIII doubling — Tilted Hub Doubling — unique to the Mint's post-1997 single-squeeze hubbing process. Here is what happens: a powerful hydraulic press imprints the design in a single downward squeeze. If the die blank sits slightly tilted in its collar as the hub descends, it "snaps" level under pressure. That snap causes the hub to drag across the die face, creating a spread. Every coin struck from that die carries the variety.
How to Identify
- Primary pickup — IN GOD WE TRUST: Focus on the letters I and N in "IN" and G and O in "GOD." A distinct spread to the east/southeast creates notching on letter corners — the letters appear slightly thicker than on a normal coin.
- LIBERTY: Check the upper serifs (the small horizontal strokes at the top of letters) on the L and I of "LIB." The VDDO-001 shows split serifs — a clean, rounded separation between two distinct serif impressions. Machine Doubling produces flat shelves here instead.
- P Mintmark: The mintmark is part of the master hub and participates in the doubling event. A "fat" or notched P is a strong supporting indicator.
- Die stages: Early die states (Stage A) show the crispest separation. As the die wears, flow lines may obscure finer detail, but the notching on TRUST typically persists through later states.
Split upper serifs on L and I of LIBERTY — a key secondary pickup point for the VDDO-001.
False Positives to Avoid
Machine Doubling is the dominant false positive — flat shelves that make letters look thinner rather than thicker. Die Deterioration shows soft, shadowy halos without crisp notching. Also note a data anomaly: one Variety Vista listing describes a "2023-P VDDO-001" with a "spread on ear and lower hair curl." A cross-reference of that listing reveals it describes a Washington Quarter variety, not a Kennedy half dollar — Kennedy's profile does not have a "lower hair curl" in that diagnostic position. Ignore any description referencing "Northwest spread on 20 of date" for Kennedy halves.
Market Values
- 🔹 Raw from circulation or bank rolls: $10–$20
- 🔹 Certified MS66: $100+ (population low; market still developing)
- 🔹 Certified MS67: $100+ (potentially significant premium as population data matures)
The GreatCollections auction archive lists a 2023-P VDDO-001 sale — check for updated results as market data accumulates. Raw examples on eBay have transacted in the $10–$20 range, with some sellers offering lots of four attributed examples to offset shipping costs.
Grading economics note: Grading fees (shipping + handling + service tier) typically exceed $40 per coin. Submitting a $15 raw coin is a financial loss. Submission is only worthwhile for pristine Uncirculated examples from Mint-direct bags that are likely to grade MS66 or higher.
Denver (D) Mint Errors
Denver struck 27,800,000 coins — by far the largest 2023 mintage — placing tremendous stress on working dies. This high-volume run has produced the VDDR-001 reverse variety and an abundance of die deterioration. The critical challenge for Denver collectors is distinguishing the scarce true doubled die from the very common die wear that pervades late-die-state examples.
2023-D VDDR-001 Doubled Die Reverse
2023-D VDDR-001 — rounded doubling on eagle design elements (right) vs. flat machine doubling (left).
How to Identify
- Examine the eagle's feathers, the bundle of arrows, and the olive branch for rounded doubling with clean, defined separation.
- Check the lettering UNITED STATES OF AMERICA and HALF DOLLAR for notching on letter corners — elements should appear thicker, not flattened or stepped.
- The doubling must add to the design. If elements look flattened, stepped, or the secondary image is a fuzzy halo, you are looking at Machine Doubling or Die Deterioration, both of which are valueless.
False Positives to Avoid
Die Deterioration Doubling is extremely common on 2023-D coins — indistinct, shadowy halos radiating toward the rim, a direct result of the massive mintage. Machine Doubling (flat shelf projections cutting into the design) is also prevalent. Neither has any collectible value. Attributed VDDR-001 examples are scarce; listings are infrequent compared to the Philadelphia VDDO-001.
Market Values
- 🔹 Raw attributed examples: $100–$120+ (asking prices observed)
- 🔹 Attributed examples are rare in the market; sellers have asked upward of $120 for confirmed attributions.
2023 Kennedy Half Dollar — Missing Clad Layer
Normal coin (left, silver-white) vs. missing clad layer (right, fully copper-red exposed core).
Origin & Background
The clad half dollar is a three-layer sandwich: outer layers of 75% copper / 25% nickel bonded to a pure copper core. This bonding happens at the metal strip supplier before blank punching. If the outer nickel-copper layer fails to bond to the copper core during strip rolling, it can peel away before the blank is punched. The resulting coin exposes the bare copper core on that side.
How to Identify
- One entire side of the coin is fully copper-red instead of the normal silver-white nickel surface. The other side appears normal.
- Weigh the coin — this is non-negotiable: A genuine missing clad layer coin weighs 9.5–9.8 g, approximately 15% less than the standard 11.34 g. The missing layer accounts for that weight deficit.
- Both the copper appearance AND the reduced weight must be present to confirm this error.
A scale showing 9.6 g confirms a missing clad layer. The standard 11.34 g means normal or post-mint damaged.
False Positives to Avoid
"Science experiment" coins dipped in acid or copper-plated after leaving the Mint will appear copper-red but weigh the full 11.34 g or more. These are post-mint alterations with zero numismatic value. A red-appearing coin that weighs 11.34 g is damaged, not an error. See the PCGS guide to missing clad layer errors for authenticated examples and further diagnostics.
Market Values
- 🔹 Generic Kennedy half dollar missing clad layer: $100–$300 depending on grade and eye appeal
- 🔹 2023-specific confirmed sales are limited due to the coin's recency; value precedent is based on the broader Kennedy series market.
2023 Kennedy Half Dollar — Struck Through Debris
A genuine struck-through error: a clearly indented, defined impression with undisturbed surrounding design.
Origin & Background
Struck-through errors occur when foreign material is trapped between the die and the planchet at the moment of striking. The two main types on 2023 Kennedy halves differ significantly in rarity and value.
How to Identify
- Grease-filled die (common, minor value): High-speed presses require lubrication. When grease mixes with metal dust and packs into the recessed letter areas of the die, those letters appear missing or faint on the struck coin. Example: a 2023 Kennedy reading "IN GOD WE T UST" with a missing R. The coin surface is slightly sunken where the letter should be.
- Struck-through debris (rare, significant value): A piece of cloth fiber, wire, or a fragment from the feeder mechanism gets trapped, leaving a distinct, clearly defined indented impression on the coin surface. The surrounding design is undisturbed — struck normally.
False Positives to Avoid
Post-mint damage (PMD) from objects contacting the coin after it left the Mint. PMD marks are typically raised (metal pushed up), scratched, or irregular in outline — not cleanly pressed into the coin's surface with undisturbed surrounding design. On genuine struck-through errors, the area immediately around the impression is fully and cleanly struck.
Market Values
- 🔹 Major struck-through debris (large, well-defined impression): $50–$200+
- 🔹 Grease-filled die (missing letters): $2–$5
2023 Kennedy Half Dollar — Clipped Planchet
Genuine clip (left) shows Blakesley Effect — rim weakness opposite the clip. Post-mint cut (right) has a sharp rim all around.
Origin & Background
A clipped planchet occurs at the blanking press when a new blank is punched overlapping a hole where a previous blank was already removed from the strip. The resulting blank has a curved, crescent-shaped section missing from its edge.
How to Identify
- A curved, crescent-shaped clip on the coin's edge that follows the circumference of an adjacent blank's punching circle.
- The Blakesley Effect — the key authentication test: Look for weakness or flatness in the rim on the side of the coin directly opposite the clip. This occurs because the missing metal at the clip site prevents the upsetting mill (which forms the rim) from applying equal pressure to the opposite side.
False Positives to Avoid
A coin with a clip but a strong, sharp rim on the side opposite the clip is almost certainly a post-mint alteration — someone applied shears or pliers to the coin after it left the Mint. No Blakesley Effect = no genuine mint error.
Market Values
Specific market data for 2023 Kennedy clipped planchets is still developing due to the coin's recency. Value depends on the size, placement, and severity of the clip as well as overall grade. Use authenticated Kennedy half dollar clipped planchet sales from the broader series as a pricing benchmark while 2023-specific records accumulate.
2023 Kennedy Half Dollar Traps: Common Misidentifications
The 2023 Kennedy half dollar's massive, high-speed production run has generated a flood of coins that look like errors but carry zero premium. Knowing these traps before you search will save you from submitting worthless coins for grading.
⚠️ Machine Doubling
A second, offset shadow of the date, Kennedy's profile, or lettering. Appears on both obverse and reverse. Extremely prevalent on 2023 halves — the most commonly misidentified "error" in the series.
After the die strikes the planchet, a loose or fatigued die bounces or shifts slightly before fully retracting. This shears the freshly formed metal, leaving a secondary shelf-like impression. It is a striking error of no collectible significance.
- The secondary image is flat and stepped — like a shelf — not rounded and notched like the primary design.
- Lettering looks thinner or narrower, not thicker or wider.
- The doubling cuts into and removes from the design rather than adding to it.
- True doubled dies (like the VDDO-001) show the opposite — rounded secondary images that make letters appear wider.
Value: Face value only.
⚠️ Die Deterioration Doubling (Especially D-Mint)
A shadowy, blurry halo or ghost image around the date or letters near the rim — especially on 2023-D coins from later die states produced toward the end of a very long run.
As a die strikes hundreds of thousands of planchets, the steel face erodes and metal flows outward toward the rim. Design elements stretch and "ghost." Denver's 27.8 million coin quota severely amplified this effect on later-state dies.
- The doubling appears as a soft, undefined halo — no crisp edges, no clean secondary image.
- It radiates outward toward the rim without a specific directional spread.
- True doubled dies have sharp, crisp notching and roundly separated secondary images; deterioration is blurry and undefined.
Value: No premium. Normal die wear from high-volume production.
⚠️ Acid-Dipped and Copper-Plated Coins
A coin with a fully copper-red surface, resembling the prized Missing Clad Layer error that can reach $100–$300.
Post-mint alteration — the coin was soaked in acid to strip the nickel-copper outer layer, or copper-plated as a novelty. Deliberate counterfeiting of this error is common because genuine examples are so valuable.
- Weigh the coin precisely. A genuine missing clad layer weighs 9.5–9.8 g. An acid-dipped coin weighs the full 11.34 g or more.
- Examine the edge. Post-mint chemical treatment often leaves uneven texture or etching on the edge that a genuine planchet error would not show.
- Weight verification is non-negotiable. Do not trust the appearance alone.
Value: Face value only.
Machine Doubling (left) shows a flat shelf that thins letters. True DDO like VDDO-001 (right) shows rounded notching that thickens them.
2023 Kennedy Half Dollar Grading: How Grade Affects Value
For the 2023-P VDDO-001 — the primary collectible variety — grade matters significantly once you cross the threshold into certified territory. Here is how grade tiers translate to value:
- Circulated (AG–EF-45): VDDO-001 examples still trade for $10–$20 raw even with visible wear. Variety recognition drives value more than grade at this tier.
- Mint State MS60–MS65: Modest premium over raw. Grading cost often exceeds return unless eye appeal is exceptional. Consider keeping these raw.
- MS66–MS67 ("Gem" grades): The viable submission tier. Certified examples can reach $100+. Focus on coins from Mint-direct bags (200-coin bags at $147.00, two-roll sets at $34.50) with full luster and minimal contact marks.
- MS68+: Potentially significant premium if population is low. Market is still developing for 2023-specific top-pop grades.
For 2023-S Proof coins, value peaks at PF69 Deep Cameo and PF70. PF68 and below sell at modest collector premiums.
Key grading focal points for Kennedy halves: Examiners focus first on Kennedy's hair above the ear and his cheek on the obverse (the highest-relief areas most susceptible to bag marks and wear), and the eagle's breast feathers on the reverse. Coins destined for high-grade certification must be free of contact marks in these critical areas.
2023 Kennedy Half Dollar Authentication: When to Get Certified
Professional authentication by PCGS (Professional Coin Grading Service) or NGC (Numismatic Guaranty Company) is not always the right call — but it is essential in specific situations for the 2023 Kennedy half dollar.
- Submit for grading when: You have a VDDO-001 or VDDR-001 in pristine Uncirculated condition likely to grade MS66 or higher, a confirmed missing clad layer, or a major struck-through debris error worth $50+.
- Do not submit when: The coin is a VDDO-001 in circulated or average Uncirculated condition. Grading fees (~$40+ including shipping) exceed the $10–$20 raw value.
- Never submit machine doubling or die deterioration: These are not mint errors. No TPG (Third-Party Grader) will attribute them as varieties, and submission costs are wasted.
💡 TPG Strategy for 2023 Kennedy Varieties
ANACS has historically been more affordable for variety attributions, making it suitable for VDDO-001 or VDDR-001 examples at the lower-grade Uncirculated tier. PCGS and NGC offer the highest resale liquidity for major errors and top-grade specimens. For missing clad layers and clipped planchets, PCGS or NGC certification is strongly recommended to maximize resale value.
Handling advice: Handle potential errors by the edges only. Never clean a coin — even rinsing with water can alter surfaces and reduce grade. Store in a non-PVC flip or hard plastic holder until submission. Any cleaning will likely result in a "Details" grade that dramatically reduces value.
Dealer buy-price information is not available in the current data. For variety attribution assistance, consult CONECA member dealers or submit queries through Heritage Auctions' numismatic research services.
2023 Kennedy Half Dollar Errors: Frequently Asked Questions
Is a 2023 Kennedy half dollar with doubling on the date or letters worth anything?
It depends entirely on the type of doubling. If the letters appear thicker with rounded, notched separation — especially on "IN GOD WE TRUST" and "LIBERTY" — it may be the VDDO-001 variety worth $10–$20 raw. If the letters appear thinner with flat, shelf-like stepped projections, you have Machine Doubling, which is worth face value only. Use a 10x loupe and compare carefully to the diagnostic images on the Variety Vista VDDO-001 detail page.
What exactly is the 2023-P VDDO-001, and how do I confirm I have it?
The VDDO-001 is Variety Vista's Doubled Die Obverse #1 for the 2023-P Kennedy half dollar, also listed as CONECA 1-O-VIII (Class VIII Tilted Hub Doubling). Confirm it by checking three things: (1) a distinct spread to the east/southeast on the I, N, G, and O of "IN GOD"; (2) split upper serifs on the L and I of "LIBERTY"; (3) a fat or notched P mintmark. All three together make a strong case. The doubling adds to the design — letters look thicker — which distinguishes it from Machine Doubling.
Why does my 2023-D half dollar look like it has doubling all over it?
Denver struck 27.8 million coins in 2023 — the largest single-mint run of the year. Dies pushed to that volume develop significant wear, which shows as Die Deterioration Doubling: indistinct, shadowy halos near the rim without crisp separation. This is extremely common on late-die-state 2023-D coins and carries no numismatic premium whatsoever. The scarce true variety, the VDDR-001, shows clean, rounded doubling with defined notching on the eagle and lettering — very different from die-wear ghosting.
My 2023 Kennedy half dollar looks copper-red on one side. Is it the missing clad layer error?
Possibly — but only if it also weighs between 9.5 g and 9.8 g. A genuine missing clad layer coin is missing one outer nickel-copper layer, which accounts for approximately 15% of the coin's total mass. The standard clad half dollar weighs 11.34 g. If your coin weighs the full 11.34 g but appears copper-red, it has been acid-dipped, copper-plated, or otherwise damaged post-mint — not a Mint error. Weight verification with a digital scale accurate to 0.01 g is non-negotiable before reaching any conclusion.
How do I tell the 2023-S clad proof from the silver proof?
Two reliable methods: (1) Edge: Tilt the coin to view the edge — a clad proof shows a visible copper-orange stripe sandwiched between two nickel-white layers; a silver proof has a uniformly brilliant white edge with no copper stripe at all. (2) Weight: Clad proof = 11.34 g; Silver proof = 12.50 g (struck in 99.9% fine silver). Silver proofs come from the Silver Proof Set and the Limited Edition Silver Proof Set (50,000-unit production cap) and are worth significantly more — $20–$40+ versus $5–$15 for clad.
Why did the Mint suddenly produce so many 2023 Kennedy half dollars?
The Federal Reserve began placing orders for half dollars again in 2021 after nearly two decades of NIFC (Not Intended For Circulation) status — during which the Mint only produced halves for numismatic collector sales, not bank distribution. By 2023 that trend had fully accelerated, resulting in Philadelphia and Denver striking a combined 44+ million coins comparable to 1980s production levels. This "Fed Order" drove the roll-hunting opportunity and the die stress conditions that make the 2023 issue notable for error collectors.
Should I send my 2023-P VDDO-001 to PCGS or NGC for grading?
Only if the coin is pristine Uncirculated and likely to grade MS66 or higher. Raw VDDO-001 examples sell for $10–$20, and grading fees (including shipping) typically exceed $40. Submitting an average Uncirculated example is a guaranteed financial loss. Exception: if you pulled a flawless Gem candidate from a Mint-direct bag, a certified MS67 could command $100+ as the market matures. PCGS and NGC provide the highest resale liquidity; ANACS may be more cost-effective for variety attributions on lower-grade examples.

While our editorial team works to ensure every image is accurate and helpful, AI-generated illustrations may occasionally misrepresent fine details.
