1902 Canadian Silver Five-Cent ('Fish Scale') Value Guide

What is your 1902 Canadian silver five-cent ('fish scale') coin worth? Complete price guide by variety (No H, Large H, scarce Small H) and grade, with Specimen values — all in CAD as of February 2026.

Quick Answer

A circulated 1902 Canadian five-cent silver coin (No H or Large H) is worth roughly $5–$25 CAD, anchored by a sterling silver melt value of approximately $3.67 CAD. The scarce Small H variety commands $15–$60 CAD in circulated grades and $1,600–$3,500+ CAD in Gem Uncirculated. Rare Coronation Specimen (SP) set coins reach $4,900–$20,000+ CAD.

  • Circulated No H or Large H (VG–VF):$5–$25 CAD
  • Circulated Small H (VG–VF):$15–$60 CAD — scarce key variety
  • Uncirculated (MS63–64, Large H):$200–$350 CAD
  • Gem Uncirculated (MS65–66, Small H):$1,600–$3,500+ CAD
  • Specimen (SP-65, Coronation Set):$4,900 CAD

Is it silver? Yes — all 1902 Canadian five-cent coins are sterling silver (.925). A magnet test confirms authenticity in seconds: genuine coins are non-magnetic. From a set? No Proof-Like (PL) issues exist for 1902; collector set coins carry a Specimen (SP) designation with a matte or satin finish — not a mirror-like field. Key identification step: Check below the date on the reverse under a 10× loupe — the presence and style of the letter "H" determines your variety and can turn a $5 coin into a $60+ collectible.

1902 Canadian five-cent silver coin obverse showing King Edward VII in Tudor Crown and Robes of State facing right, with EDWARDVS VII D.G. REX IMPERATOR legend, portrait by George William De Saulles

Obverse of the 1902 Canadian five-cent silver coin ('fish scale'): King Edward VII in the Tudor Crown and Robes of State, portrait by George William De Saulles. The IMPERATOR legend — acknowledging the King's status as Emperor of India — debuted on Canadian coinage with this first Edwardian issue.

The 1902 Canadian five-cent silver piece — nicknamed the "fish scale" for its tiny, thin form — marks the definitive arrival of the Edwardian era in Canadian coinage: the first year bearing King Edward VII's portrait and the bold new IMPERATOR legend. Production was divided between the Royal Mint in London (no mint mark) and Ralph Heaton & Sons in Birmingham (distinguished by an "H" mint mark), giving rise to the No H, Large H, and scarce Small H varieties that drive collector competition to this day. This guide covers CAD valuations for every documented variety, grade, and finish. For values spanning all years of the 5-cent series, see our Canadian Nickel Value Guide.

1902 Canadian Five-Cent Silver Composition & Melt Value

1902 Canadian Five-Cent Silver Specifications
Weight: 1.162 g (approx. 18 grains) | Sterling Silver (.925 Ag / .075 Cu) | Diameter: 15.5 mm | Reeded (milled) edge | Coinage alignment (↑↓) | Non-magnetic

The 1902 Canadian five-cent piece is struck in sterling silver — an alloy of 92.5% silver and 7.5% copper. The copper content was added for durability, as pure silver is too soft for coins intended to circulate actively. Canada maintained this silver five-cent standard without interruption until the denomination was suspended in 1921 and relaunched in a pure-nickel composition in 1922, meaning every example dated 1902 is unambiguously a silver coin.

At just 1.162 grams and 15.5 mm in diameter, the 1902 five-cent piece was the smallest and thinnest denomination in Canadian commerce of its era — earning the enduring nickname "fish scale" because the coins were easily lost, difficult to handle with gloved hands, and resembled fish scales when handled in bulk.

Melt Value (February 2026)

Based on silver spot prices of approximately $3.43 per gram CAD in early 2026, the intrinsic melt value of a 1902 five-cent coin is approximately $3.67 CAD. This silver floor is numismatically significant: even a worn, heavily damaged, or dateless example retains meaningful bullion value, preventing discarding but also creating a risk of smelting for base-grade coins during periods of elevated silver prices. Current silver spot data can be tracked at Canada Gold's live silver price page.

Magnetic Test — First-Line Authentication

Sterling silver is non-magnetic. Hold any magnet — even a common refrigerator magnet — to the coin. A genuine 1902 five-cent coin will show zero attraction. Any pull toward a magnet indicates a modern counterfeit (typically steel-plated) or an anomalous wrong-planchet piece. This three-second test should precede any purchase of a raw (ungraded) 1902 five-cent coin. Because the coin's small size and silver color can visually mimic some modern coins, the magnet test is the fastest and most reliable first authentication step available to any collector.

1902 Canadian Five-Cent Silver Value Chart by Variety & Grade

All values are in Canadian dollars (CAD) as of February 2026, synthesized from auction records and numismatic catalogues. Three distinct business-strike varieties — No H, Large H, and Small H — each carry significantly different premiums. The Specimen (SP) finish represents a completely separate tier reserved for advanced specialists. Values assume problem-free, original-surface coins; cleaned examples typically trade at a 30–50% discount.

ℹ️ The MS60–62 Range — Beware of "Sliders"

The $75–$150 CAD range for MS60–62 attracts coins that are actually AU-58 "sliders" — pieces that nearly reached Mint State but show the faintest rub on the highest points. On a coin as small and thin as the 1902 five-cent, the difference between AU-58 and MS-60 can be invisible without a loupe. For coins in this price tier, third-party certification (ICCS, PCGS, or NGC) is strongly recommended before purchase above the $100 CAD mark.

⚠️ Never Clean Your Coins

Cleaning strips original luster and leaves hairlines visible under magnification. A cleaned 1902 five-cent coin is graded "Details" (damaged) and typically sells at a 30–50% discount to problem-free values at the same grade — regardless of how sharp the underlying detail may be. The fish scale market is unforgiving of altered surfaces.

(Illustration — not a photo of your exact coin)

The Royal Mint produced a small number of Specimen (SP) five-cent coins for commemorative Coronation presentation sets. These are always the No H (London Mint) variety — no Heaton Mint Specimen issues are documented for 1902. Specimen coins differ visibly from business strikes: the fields carry a matte or satin sheen rather than cartwheel luster, the rims are sharper and more squared from double-striking, and the devices display exceptional definition. Complete Coronation sets are extremely rare; individual SP coins appear only occasionally at specialist auctions. No Proof-Like (PL) issues exist for this year.

Most Valuable 1902 Canadian Five-Cent Silver Varieties

The 1902 Canadian five-cent series offers a clear hierarchy of varieties, from the affordable and abundant London issue to museum-quality rarities that appear only occasionally on the open market. Identifying your variety is the single most important step in determining your coin's true value.

Trophy-Level Varieties

1. 1902 Specimen (SP-67) — The Ultimate Prize

A Specimen-grade 1902 five-cent coin certified SP-67 is valued at over $20,000 CAD — the apex of this date. These exist in vanishingly small numbers as part of the Royal Mint's Coronation presentation sets. They are always the No H (London) variety. Even an SP-65 is a significant acquisition at $4,900 CAD, representing a coin produced with the highest possible care and preserved in essentially perfect condition for more than a century.

2. 1902 Small H (MS65–66) — Investment-Grade Key Variety

The Small H in Gem Uncirculated condition is the trophy within reach for the serious Edward VII collector. In MS65–66, auction records document prices of $1,600–$3,500+ CAD. The rarity stems from the Small H's estimated share of only 10–15% of the total Heaton Mint production — a small fraction of the 2,200,000 Heaton coins — compounded by the extreme difficulty of preserving these thin, soft sterling silver pieces in Gem condition. Even at MS63–64, the Small H commands $400–$800 CAD, roughly double its Large H counterpart. Recent demand is documented in the TCNC Prominence Sale XI catalogue (November 2024).

3. 1902 Large H over Small H (RPM) — Rare Die Variety

This Repunched Mint Mark (RPM) variety is cataloged as a distinct variety in major references including the Charlton Standard Catalogue. It originated from a die correction: a Small H (sans-serif) punch was applied first, then corrected with the Large H (serifed) punch. The tell-tale diagnostic is a small "spike" or "horn" protruding from the top of the Large H — the underlying Small H punch visible beneath. Because this variety is believed to originate from a single die pair, it is extremely scarce. Even examples in low grades (G-6) sell immediately upon appearing on the market. No single standard catalogue price is established; it is acquired primarily through specialist auction and private treaty.

💡 Buying Strategy (from the document)

For type sets: A 1902 No H in MS63 offers the best balance of beauty and affordability in the $200 range. For variety collectors: The Small H in AU-55 or MS60 represents strong value — the spread between AU and Gem MS is dramatic, suggesting "just missed" uncirculated coins offer significant upside. Avoid low-grade (G/VG) examples unless filling a folder hole — the premium over melt is negligible and liquidity is low.

1902 Canadian Five-Cent Silver Identification Guide

Use this checklist to authenticate your coin, identify its variety, and determine its finish — the three steps that establish its true market value.

Reverse of the 1902 Canadian five-cent coin: the 22-leaf maple bough wreath frames the central "5 CENTS," with the St. Edward's Crown at top and the date "1902" below. The mint mark location — immediately below the date, between the ribbon ends — is highlighted. No letter = London Mint; "H" = Heaton (Birmingham) Mint. (Illustration)

30-Second Identification Checklist

  1. Monarch Check: The obverse should show King Edward VII facing right, wearing the Tudor Crown and Robes of State. The portrait was engraved by George William De Saulles and is noted for its realistic, unidealized depiction of the King's features. The legend reads EDWARDVS VII D.G. REX IMPERATOR. If any other monarch appears, the coin is not a 1902 five-cent.
  2. Reverse Check: A maple bough wreath of 22 leaves surrounds the central numeral "5" flanked by "CENTS." The St. Edward's Crown surmounts the top gap of the wreath. The date "1902" appears at the bottom. The Leonard C. Wyon reverse motif continued from the Victorian era.
  3. Date Check: Confirm "1902" clearly. On heavily worn examples where the date is partially legible, the coin's value is near melt only.
  4. Edge Check: The edge is reeded (milled). A plain-edged example is not genuine.
  5. Magnet Test — Critical Authentication Step: Touch a magnet to the coin. A genuine 1902 five-cent coin is completely non-magnetic (sterling silver). Any attraction indicates a modern counterfeit. Perform this test before any other examination on an unknown coin.
  6. Mint Mark Check: Flip to the reverse and examine below the date "1902," between the ribbon ends of the wreath.
    • No letter present: London Mint (No H variety). Most common. Proceed to grading.
    • Letter "H" present: Heaton Mint (Birmingham). Proceed to Step 7.
  7. Variety Check — The Serif Test (10× loupe required): Examine the vertical uprights of the "H" carefully.
    • Serifs visible (horizontal feet at the base, small caps at the top of each vertical bar): Large H — common Heaton variety.
    • No serifs — plain, straight bars:Small H — scarce key variety. Verify condition meticulously; this is the valuable one.
    • Serifed H with a spike or horn protruding from its top-center:Large H over Small H (RPM) — rare die variety. Seek specialist authentication.
  8. Finish Identification:
    • Business Strike: Cartwheel luster — a rolling, wheel-like light effect across the fields as the coin is rotated. Fields may carry bag marks and contact marks from handling.
    • Specimen (SP): Matte or satin fields — no cartwheel effect. Fields appear uniformly granular or silky. Rims are noticeably sharper and more squared. Devices show exceptional, almost sculptural detail. Always No H (London Mint). Specimen coins come from Coronation presentation sets, not from circulation.

The concave reverse mechanism: a slightly convex reverse die (left) strikes the planchet, creating a dish-like depression on the coin's reverse (center). This forces the obverse portrait's ear and cheekbone higher — they wear first and fastest — while the recessed reverse retains superior detail (right). Always evaluate both sides of a 1902 five-cent before assigning a grade. (Illustration)

The Concave Reverse — A Critical Grading Complication

A significant number of 1902 five-cent dies were manufactured with a slight convexity, resulting in struck coins with a concave (dish-like) reverse. This production anomaly has a direct and significant impact on grading:

  • The concavity of the reverse die pushes the metal on the obverse — particularly the King's ear and cheekbone — outward, elevating these already-prominent high points further above the rim.
  • The ear therefore contacts surfaces first and wears fastest, even after only brief circulation.
  • The concave reverse itself is protected by its depression; leaves and ribbon detail may survive at EF or AU quality even when the obverse reads Fine.

Expert guidance: Do not grade a 1902 five-cent coin by the obverse ear alone. If the ear is flat but the reverse leaves show clear vein separation and the ribbon retains fine detail, you are likely examining a high-grade concave reverse strike, not a worn Fine. Conservative grading services such as ICCS may still penalize the coin for the missing ear detail; however, market participants familiar with this anomaly often recognize the superior reverse and pay a premium accordingly. Reference documentation on this variety is discussed at Calgary Coin's Canadian five-cent reference.

Surface Preservation Notes

Toning: Sterling silver is reactive. London-struck 1902 coins tend to develop slate-grey or light champagne toning over time. Heaton-struck coins are observed to develop more vivid iridescent toning — blues, russets, and violets — possibly due to trace impurities in the Birmingham alloy or die lubricants used at that facility. Original, naturally toned surfaces command a premium; artificial toning is a grading-service disqualifier.

Die Polish Lines — London Mint: London dies were often extensively polished, leaving raised parallel lines (die polish lines) in the coin's fields. These are raised lines that run uniformly in one direction and do not disturb the design. Do not confuse them with cleaning hairlines, which are incuse (cut into the surface) and run in random directions across the fields.

ℹ️ Grading Services — ICCS vs. PCGS vs. NGC

ICCS (International Coin Certification Service) is the Canadian standard and is highly respected within the Edward VII silver series. PCGS and NGC are US-based services with active population registries and online price guides that cover Canadian coins. The NGC Canada 5 Cents KM#9 (1902) price guide covers all major varieties. An example of an ICCS-certified MS-65 specimen from 1902 is documented at Coins Unlimited.

1902 Canadian Five-Cent Silver Value FAQs

What is a 1902 Canadian five-cent coin worth?

Value depends entirely on variety and grade. A circulated No H or Large H is worth approximately $5–$25 CAD, anchored by a silver melt value of ~$3.67 CAD. The scarce Small H variety commands $15–$60 in circulated grades. In Mint State, values range from $75–$150 (MS60–62, all common varieties) through $200–$350 (MS63–64, Large H) to $1,600–$3,500+ (MS65–66, Small H). Coronation Specimen (SP) set coins represent the pinnacle at $4,900 (SP-65) to $20,000+ (SP-67) CAD.

How do I identify the No H, Large H, and Small H varieties?

Examine the reverse of the coin below the date "1902" under a 10× magnifying loupe. If no letter appears, you have the London Mint "No H." If an "H" is present, examine the vertical uprights of the letter: clear serif feet and caps on the bars = Large H (common); plain, straight bars with no ornamentation = Small H (scarce, key variety). If the serifed Large H also shows a small spike or horn protruding from the top-center of the letter, you may have the rare Large H over Small H RPM variety cataloged in Charlton.

Is my 1902 Canadian five-cent coin silver?

Yes, without exception. Every 1902 Canadian five-cent coin is sterling silver (.925 silver, .075 copper). Canada did not transition the five-cent denomination to a base-metal composition until 1922, so all 1902 examples are silver coins. Confirm authenticity instantly with a magnet: genuine 1902 five-cent coins are completely non-magnetic. Any magnetic attraction indicates a counterfeit.

What is the melt value of a 1902 Canadian five-cent coin?

Based on silver spot prices of approximately $3.43 per gram CAD in early 2026, the intrinsic melt value is approximately $3.67 CAD per coin. This silver floor means even a heavily worn, dateless, or damaged example has baseline economic value. For any identifiable variety in VG condition or better, numismatic value exceeds melt value substantially — the Small H at VG-8 alone commands $15–$25 CAD, or roughly four to seven times the bullion floor.

What is the "concave reverse" and does it affect my coin's grade?

A significant number of 1902 dies were manufactured with a slight convexity, producing coins with a dish-like depression on the reverse. This forces the obverse portrait's ear and cheekbone higher than normal, causing them to wear first and fastest. A coin may appear to be VG or Fine by its obverse ear alone while its reverse retains EF or better detail on the leaves and ribbon. Conservative grading services may penalize the coin for the flat ear, but the market often recognizes the superior reverse and pays a premium. Always evaluate both obverse and reverse before assigning or accepting a grade on a 1902 five-cent coin.

What is a Specimen (SP) 1902 five-cent coin?

Specimen coins were produced by the Royal Mint in London as part of commemorative Coronation presentation sets. They are always the No H (London Mint) variety — no Heaton Specimen issues are documented for 1902. Unlike business strikes, Specimen coins carry a matte or satin finish rather than cartwheel luster, have sharper and more squared rims, and show exceptional device detail from double-striking. Complete Coronation sets are extremely rare; individual SP coins appear only occasionally at specialist auctions. No Proof-Like (PL) issues exist for this year.

Should I get my 1902 five-cent coin graded by ICCS, PCGS, or NGC?

Grading fees are only economically recoverable when the coin's certified value substantially exceeds the cost of submission. For common No H or Large H coins in VG to VF grades ($5–$25 range), grading is not cost-effective. The calculation changes meaningfully for: (1) any coin that appears to be MS60 or better; (2) any coin showing a sans-serif "H" (potential Small H); (3) any coin showing a spike above the "H" (potential RPM); or (4) any coin with a matte/satin surface suggesting Specimen status. ICCS is the Canadian standard for Edward VII silver; PCGS and NGC offer US-based certification with active population registries.

What does the "IMPERATOR" legend on the 1902 coin mean?

The obverse legend reads EDWARDVS VII D.G. REX IMPERATOR — "Edward VII, by the Grace of God, King and Emperor." The title Imperator acknowledged the British monarch's status as Emperor of India, a title held since 1876. The 1902 Canadian issue was the first year this Imperial title appeared explicitly on Canadian silver coinage, making the coin a historically significant first-year type that attracts typological collectors beyond the variety specialist market.

Why is the Small H so much more valuable than the Large H?

The Small H is estimated to represent only 10–15% of the Heaton Mint's total 1902 production of 2,200,000 coins — likely a small fraction struck from dies prepared using a different, non-standard sans-serif punch, possibly an older or replacement punch available at the Birmingham facility. This relative scarcity within the total mintage, compounded by the extreme difficulty of these thin silver coins surviving in Gem Mint State condition, creates dramatic premiums: at MS65–66, a Small H ($1,600–$3,500+) commands roughly double to quadruple the value of a Large H ($650–$1,000+) in the same grade, with the gap widening further in the very finest condition.
