Mexican .900 Silver Ten Pesos — Actual1955–1960 Issues

A matching Mexican .900 silver ten pesos contains 0.8356 reference fine silver troy ounce using the designated reference melt table. Actual included years are 1955–1957 and 1960. Confirm denomination, complete date, both designs, nominal 28.88 g mass and 40 mm diameter before combining a quantity. Different Mexican coins sharing the denomination can contain different amounts of silver.

When a fresh spot bid is available, melt values use fine-metal content × spot bid. CashForCoins guide buying offers use the separately configured percentage for each metal. Selected rare/numismatic coins require an appraisal. Dollar amounts remain unavailable when a fresh quote or buying percentage is missing.

Exact reviewed annual face/issue years for the assigned standard, retaining mint and design gaps. Overdate undernumerals and commemorative life dates do not add annual issues. Separate alloys, weights, designs and finish availability are explained in the guide.
Source precision: The reference’s designated World Silver melt reference supplies 28.88 g gross mass, 0.9 fineness and 0.8356 fine silver troy ounce. Matching dated KM 474, 475 and 476 records supply actual dates, 40 mm diameter, identity, designs and mint notes. The designated melt group supplies 28.88 g/.900/.8356 ASW. Dated KM 474 and 476 give 28.888 g/.900/.8359; KM 475 gives 28.88 g/.900/.8357. These conflicting reference precisions do not alone prove a separate physical standard. Preserve designated calculation inputs and record every dated value openly; no exact revised weight or fine-metal amount is invented. Thickness and identities of remaining alloy metals have not been independently verified.

Calculate this coin’s metal content

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

Obverse: identify the front

The reference describes the national arms on the 1955–1956 type and an eagle-left national-arms design on the 1957 and 1960 commemoratives. The denomination, date, visible mass/fineness legends and whole reverse design must match the selected type.

Reverse: identify the back

KM 474 has a left-facing head in 1955–1956. KM 475 has a left-facing head with Constitution-centenary subject in 1957. KM 476 has conjoined facing busts flanked by commemorative dates in 1960. The different portraits and subjects must be described separately.

History and purpose

Actual silver issues within this group are 1955, 1956, 1957 and 1960. Hidalgo KM 474 is dated 1955–1956. KM 475 commemorates the Constitution centenary in 1957. KM 476 commemorates the 150th anniversary of the War of Independence in 1960. Gold ten pesos belong to a separate metal standard.

How to identify this variant

Match the complete 10 pesos denomination and included issue years. The designated standard is 28.88 g gross mass, 0.9 silver fineness and 40 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 86.64 nominal gross grams and 2.5068 reference fine silver troy ounces. The calculator uses 0.8356 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

Specific annual years are 1955, 1956, 1957, 1960. KM 474 lists 1955 and 1956 with a reeded edge; KM 475 lists 1957 and INDEPENDENCIA Y LIBERTAD edge lettering; KM 476 lists 1960 with a reeded edge. Edge treatment varies by design and should not be homogenized across this group.

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 10 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 available, when requesting a CashForCoins appraisal. Preserve possible overdates and unusual die details for individual review. An offer can depend on authenticity, condition and collector demand alongside metal content. The reference melt calculation is an educational estimate.

Sources and calculation methodology

The designated reference melt table gives 28.88 g gross mass, .900 fineness and 0.8356 fine silver troy ounce. Dated KM 474 and KM 476 records give 28.888 g and 0.8359 oz; KM 475 gives 28.88 g and 0.8357 oz. These reference differences are disclosed while retaining the designated 0.8356 oz calculation. They do not by themselves establish different physical alloy variants. Dated annual rows establish 1955, 1956, 1957 and 1960, with design-specific edge treatments described above. Thickness and the proportions of remaining alloy metals are unspecified.

Common questions

Which actual issue years are covered?

1955–1957, 1960. Matching annual rows establish the list; omitted years are not inferred.

How much silver is in three matching coins?

2.5068 reference fine silver troy ounces and 86.64 nominal gross grams, using the designated reference. This does not authenticate a specimen or establish collector value.

Can other coins with the same denomination have another metal amount?

Yes. Identify the actual dated type, metal, nominal mass and fineness before combining a quantity. Different alloy standards and gold or base-metal coins require separate calculations.
