Mexican Second Republic Gold Ten Pesos — Actual Years and .875 Gold
Normal Mexican Second Republic gold ten pesos use the reference standard of 16.92 g gross, .875 fineness and .4760 fine gold troy ounce. Actual reviewed engraved years are 1870–1895, 1897–1898, 1900–1905. Read the complete 10-peso value and cap/scales reverse before assigning this standard. Later Mexican gold denominations can share the same face amount while having another mass, purity and design.

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.

- Source precision
- The reference designated World Gold retains 16.92 g/.875/.4760 reference AGW for normal historical 10 pesos. Detailed Numista dated catalog rows establish the accepted annual union 1870–1895, 1897–1898, 1900–1905; market prices and mintages are excluded. No1896 or1899 normal row is listed for the ten-peso family. Ten matching reference mint-type search records were observed, while their complete annual details remain for cross-check. Neither a universal diameter nor thickness is established by the inspected matching records. No dimension or photographic permission is invented.
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 normal the reference types describe a facing eagle with a snake in its beak. REPUBLICA MEXICANA identifies the republic around the national emblem. Eagle details can vary between dies and mints; a familiar Mexican emblem alone does not identify metal, denomination or the correct historical standard. Keep the full rim, legends and the opposite face available when comparing a specimen with a catalogued issue.
Reverse: identify the back
The cap/scales type carries a radiant liberty cap above scales, with further law-and-sword detail and the 10-peso wording. Record the actual mint and assayer characters as well as the .875 fineness marking where visible. The smaller historical one- and two-and-a-half-peso gold value reverses differ. A denomination or eagle image alone does not distinguish this large historical standard from later .900 gold pesos.
History and purpose
Mexico’s decimal Second Republic gold coinage included several peso denominations and regional mint/assayer combinations. This guide groups matching normal metal standards while preserving each dated mint variety for identification. Later .900 gold pesos and modern bullion belong to different coin families. A denomination reused in another period is not evidence that the same historical gold-content calculation applies.
How to identify this variant
Confirm the Second Republic gold type, 10-peso denomination, national eagle, cap/scales reverse, full date and mint/assayer combination. The reference reports 16.92 g gross and .875 gold. Physical diameter and edge still require a matching reference; no universal dimension is guessed. A later same-denomination coin is not assigned this heavier historical gold standard solely because its peso amount matches.
Understanding its metal content
The reference reports .4760 reference fine gold troy ounce per matching normal coin. Three pieces total 1.4280 reference fine ounces and 50.76 nominal gross grams. Gross mass times .875 gives 14.80500 fine grams per coin, approximately 0.475992 troy ounce. This arithmetic is disclosed separately from the rounded designated AGW. Unspecified alloy remainder is not additional gold, and a worn specimen requires individual assessment.
Dates, varieties and composition changes
Accepted actual engraved years are 1870–1895, 1897–1898, 1900–1905. The detailed annual rows omit 1896 and 1899, which are not filled from the broad 1870–1905 heading. Mint-type distinctions include Álamos, Chihuahua, Culiacán, Durango, Guadalajara, Guanajuato, Hermosillo, Mexico City, Oaxaca and Zacatecas; an individual mint did not strike every family year. Retain complete overdates and mint/assayer attributions without inventing a scarcity grade, die-error identity or premium.
Melt value versus collector value
A dated regional mint issue, overdate or die combination may need individual numismatic appraisal before a metal-content sale. Preservation, cleaning, mounting and retained certification affect that assessment. This guide assigns no grade, scarcity claim, current catalog price or expected premium. Keep each coin’s full attribution and original surfaces intact instead of treating an unexamined historical lot solely as scrap.
Authenticity and condition
Photographs, yellow color and a scale reading cannot authenticate a coin by themselves. Document the complete faces, rim and edge without cleaning, acid testing or scraping. Confirm the catalogued date/mint combination and obtain the missing physical reference dimensions where needed. Exclude uncertain pieces, altered denominations and unidentified replicas from a confirmed nominal collection total until examined.
Selling this coin
Separate these .875 Second Republic gold issues from later .900 pesos, silver pesos and modern bullion. Supply dated mint/assayer notes, full-rim both-side photographs and any original certification through the existing CashForCoins appraisal process. A nominal fine-gold quantity helps describe a lot; it is not a guaranteed offer. Missing market-provider data must remain unavailable rather than displaying a zero-dollar melt value.
Sources and calculation methodology
The reference designated World Gold retains 16.92 g/.875/.4760 reference AGW for normal historical 10 pesos. Detailed Numista dated catalog rows establish the accepted annual union 1870–1895, 1897–1898, 1900–1905; market prices and mintages are excluded. No 1896 or 1899 normal row is listed for the ten-peso family. Ten matching reference mint-type search records were observed, while their complete annual details remain for cross-check. Neither a universal diameter nor thickness is established by the inspected matching records. No dimension or photographic permission is invented. Metal inputs remain from the user-designated reference table rather than another catalog’s substitute. Actual dated rows are distinct from an envelope of possible years, and unconfirmed entries do not establish varieties.
Common questions
Does a Mexican peso denomination identify its metal?
No. Mexican pesos include distinct silver and gold families. Match the full dated type, denomination and material before calculating metal content.Did every mint issue every year listed?
No. The family years are the union of actual dated mint records. An individual mint or finish must be checked separately.Can later .900 Mexican gold use this .875 record?
No. Later issues have separately documented weights and purities and need their own coin identity and calculation.References
