Obverse: identify the front

The reference describes the eagle-left national arms within a wreath. This commemorative silver 2 peso must not be confused with the smaller gold 2 peso issues that also carry Mexican national arms.

Reverse: identify the back

The matching reverse depicts Winged Victory. A 2 peso denomination, 1921 commemorative identity and the nominal 26.6667 g, .900 silver standard are required before applying this calculator.

History and purpose

The reference identifies KM 462 as the Centennial of Independence issue and lists 1921 as its single annual year. Its nominal .900 silver standard contains .7716 fine silver troy ounce; a gold 2 peso and a later base-metal 2 peso have different metal and mass despite the same denomination.

Casa de Moneda de México describes the 1921 silver two pesos as a centenary issue marking the completion of Mexican independence. It distinguishes this silver centenary coin from the larger-denomination gold fifty-peso centenary coin.

How to identify this variant

Match the complete 2 pesos denomination and included issue years. The designated standard is 26.6667 g gross mass, 0.9 silver fineness and 39 mm diameter. Keep unrelated alloys, gold coins, regional issues, patterns and replicas separate. Wear can reduce mass; appearance, a magnet or a household scale cannot alone determine precise alloy or authenticate the coin.

Understanding its metal content

Three matching coins contribute 80.0001 nominal gross grams and 2.3148 reference fine silver troy ounces. The calculator uses 0.7716 oz per coin rather than treating total alloy mass as pure silver. Dollar melt pricing requires an approved current market quote; absent pricing is not shown as zero. Collector demand and condition remain separate from metal content.

Dates, varieties and composition changes

The actual annual issue year is 1921. The commemorative Roman numerals MDCCCXXI and MCMXXI refer to 1821 and 1921, the centenary dates; they do not establish an 1821 issue of this coin. The reference’s dated KM 462 table supplies 1921 only. Match the complete silver two-peso design and distinguish gold two pesos and later base-metal coins.

Melt value versus collector value

An attributed overdate, die variety, date, finish, condition or provenance may influence collector interest independently of silver content. The metal calculation cannot determine grade, rarity or collector value. Avoid polishing or cleaning; preserve original surfaces, any established provenance and reputable certification. A worn piece and an uncirculated example of the same nominal standard can have different collector values.

Authenticity and condition

A photograph of another denomination or alloy must not be used as this type’s illustration. Complete authentic obverse, reverse and edge views, measured mass and diameter help investigate a specimen but are not a silver assay. Plated pieces, cast copies, unlisted patterns and doubtful dates require individual attribution. Avoid cleaning or inferring a proof finish from shine.

Selling this coin

Sort 2 pesos coins by complete date, design and nominal metal standard before entering quantities. Send clear photographs of both sides, plus edge photographs and measured weight where possible, when requesting a CashForCoins appraisal. Preserve unusual die details for individual review. An offer can depend on authenticity, condition and collector demand alongside metal content. The melt calculation is an educational reference.

Sources and calculation methodology

The reference’s designated World Silver melt reference supplies 26.6667 g gross mass, 0.9 fineness and 0.7716 fine silver troy ounce. Matching dated KM 462 records supply actual dates, 39 mm diameter, identity, designs and mint notes. Thickness and identities of remaining alloy metals have not been independently verified. Actual annual years come from dated catalog rows. The reference fine-silver amount applies to a correctly attributed coin and does not establish authenticity, grade or collector value.
