Mexican Silver Five Pesos — 18.05 g .720 Types

The lighter Mexican .720 silver five pesos use 18.05 nominal gross grams and 0.4178 reference fine silver troy ounce. Three inspected types establish 1955–1957 and 1959, retaining the 1958 gap. They include Hidalgo, the Constitution centennial and Carranza’s birth centennial. The genuine 1959 pair represents Carranza KM471; the commemorative 1859 date is not its issue year.

Four actual family years: Hidalgo KM469 in 1955–1957, Constitution KM470 in 1957, Carranza KM471 in 1959. No 1958 annual row occurs in the inspected types. The Carranza commemorative 1859 date is not an issue date. Edges vary by type; heavier silver standards and gold coins remain separate.

Source precision
The designated melt table and all three dated types agree on 18.05 g/.720/.4178 ASW and a 36-mm diameter. The shared years retain the 1958 gap. KM471 specifies a plain edge; KM470 records INDEPENDENCIA Y LIBERTAD; no edge is independently verified for KM469 from the inspected page. Thickness and remaining alloy-metal identities are unverified.

Calculate this coin’s metal content

One coin contains 0.4178 troy oz of fine silver.

Formula: specified fine-metal troy ounces × quantity. Dollar melt value additionally requires an approved current metal price.

Obverse: identify the front

The national-arms obverse is on the right in the original paired photograph. It shows the eagle, ESTADOS UNIDOS MEXICANOS, CINCO PESOS, the 1959 issue date and LEY 0.720. The reference identifies this face as obverse. A national-arms emblem occurs on other Mexican coins, so read the actual denomination, date and standard together.

Reverse: identify the back

The pictured Carranza reverse shows his head facing left, with beard and spectacles, AÑO DE CARRANZA, the dates 1859–1959 and Mo. The first date commemorates his birth; the coin’s annual issue is 1959. Hidalgo and Constitution-centennial pieces have different portraits/legends despite sharing the lighter .720 standard.

History and purpose

The lighter standard separates these five pesos from the earlier 27.78-g .720 coins. KM469 lists Hidalgo issues in 1955–1957, KM470 is the 1957 Constitution centennial, and KM471 is the 1959 Carranza centennial. The reference’s broad melt heading ends in 1959, but the actual dated records do not establish an intervening 1958 issue.

How to identify this variant

Confirm CINCO PESOS, the actual issue date, portrait/commemorative legend and nominal .720 standard. The three included tables agree on 18.05 g and 36 mm. Edges differ: Carranza is plain, the Constitution piece has its own recorded lettering, and KM469’s inspected page provides no edge specification. Do not classify a gold five pesos or the heavier silver families by denomination alone.

Understanding its metal content

One matching coin contributes 0.4178 reference fine silver troy ounce. Three contribute 1.2534 fine silver ounce and 54.15 nominal gross grams. Nominal silver mass follows gross mass × fineness; the designated reference supplies the stated rounded ounces. Use only coins matching this exact standard. Worn, plated or altered pieces require separate assessment.

Dates, varieties and composition changes

Actual source-supported family issue years are 1955–1957, 1959. Designs remain attributed to their dated types.

KM469 — Hidalgo, 1955–1957

Specific annual rows list 1955, 1956 and 1957. The lighter portrait type must not inherit the heavier KM467 silver amount.

KM470 — Constitution centennial, 1957

The single annual issue is 1957. Its INDEPENDENCIA Y LIBERTAD edge lettering is separately recorded by the reference.

KM471 — Carranza centennial, 1959

The annual issue is 1959, with a plain edge. The genuine pair shows this type. The printed 1859 commemorative date is not an extra coin issue year.

Melt value versus collector value

Retain the precise portrait, reverse legends, edge and issue date with each specimen. A 1957 date can belong to the Hidalgo or Constitution type. The 1859 date on the Carranza reverse describes its subject, not the minting year. Reference silver content is not a collector valuation or an authentication result; preserve surfaces and any provenance labels.

Authenticity and condition

Provide complete photographs of both faces, the full issue date and denomination, the edge, and actual measured mass/diameter when available. These genuine reference photos help identify a design; they do not authenticate, grade or assay another specimen. Keep unresolved pieces separate until attributed.

Selling this coin

Sort this exact five-peso composition away from other weights, purities, gold coins, replicas and unresolved specimens. Use the existing photo-appraisal link with the selected quantity for collection details and photographs. Live dollar pricing is unavailable until a provider is approved. Reference metal content is not a purchase offer or guaranteed recovery amount.

Sources and calculation methodology

The designated melt table and all three dated types agree on 18.05 g/.720/.4178 ASW and a 36-mm diameter. The shared years retain the 1958 gap. KM471 specifies a plain edge; KM470 records INDEPENDENCIA Y LIBERTAD; no edge is independently verified for KM469 from the inspected page. Thickness and remaining alloy-metal identities are unverified. Actual annual rows and independent photographic permissions were inspected on 2026-10-11. The genuine reference faces illustrate 1959 KM471 Carranza five pesos only. Full photographs are converted to WebP without upscaling or invented artwork; source faces and any pair splitting are disclosed in the credits. Face labels follow the inspected reference design convention, not filenames. No reference prices, mintages or descriptive articles are copied.

Common questions

Is the Carranza coin dated 1859 or 1959 for this calculator?

Its inspected annual issue is 1959. The reverse’s 1859–1959 inscription commemorates Carranza’s birth centennial; 1859 is not added as an issue year.

How much reference silver do three matching coins contain?

Three contain 1.2534 fine silver troy ounce and 54.15 nominal gross grams using this exact standard. Live dollar value requires an approved current silver price.

Can another five-peso denomination use this silver amount?

Only if it matches this verified composition and dated design. Other five-peso weights, purities and gold issues require their own records.
