Mexico • 5 pesos
Normal Mexican Second Republic gold five pesos contain .2380 reference fine gold troy ounce at 8.46 g gross and .875 fineness. Verified actual years are 1870–1884, 1886–1895, 1897–1898, 1900–1905. The radiant-cap-and-scales reverse distinguishes this denomination from the smaller gold one and two-and-a-half pesos. Later .900 five pesos have another mass and fine-gold quantity, even though the denomination is the same.
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.
Actual source-reviewed issue years for this exact denomination, design and metal/weight scope. Overdates, mint combinations and proof availability remain type-specific; specimen photos and measurements do not certify other examples.
Formula: specified fine-metal troy ounces × quantity. Dollar melt value additionally requires an approved current metal price.
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.
The reference describes a radiant cap above scales for each matching normal five-peso mint type. Identify the complete 5 PESOS denomination, date and mint/assayer combination rather than relying on the national eagle alone. This design should not be replaced with the smaller denominations’ half-wreath value reverse. Complete rim photographs preserve the details needed to attribute an overdate or regional mint issue.
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.
Read 5 PESOS, the radiant cap and scales, the full dated mint/assayer combination and REPUBLICA MEXICANA. The normal reference mass is 8.46 g and the gold fineness is .875. A later Mexican .900 five-peso design is a separate standard. Physical diameter and edge still require a matching primary reference; those unknown dimensions are not fabricated. Color and mass alone do not authenticate an individual specimen.
The reference reports .2380 reference fine gold troy ounce per matching normal five pesos. Three correctly identified coins total .7140 reference fine ounces and 25.38 nominal gross grams. Mass times .875 gives 7.4025 fine grams per coin, approximately 0.237996 troy ounce. This arithmetic is disclosed separately from the rounded designated AGW. The alloy remainder is not additional gold, and a worn or damaged coin requires individual assessment.
Accepted actual engraved issue years are 1870–1884, 1886–1895, 1897–1898, 1900–1905. No 1885, 1896 or 1899 year is established by the inspected annual tables. Mexico City supplies many years with overdates including 1871/69, 1873/2, 1875/3, 1876/5, 1878/7 and 1879/8. Guanajuato lists 1871 and 1887; its separately selected 1893GoR row is marked rare. Other matching mint types include Álamos, Chihuahua, Culiacán, Durango, Hermosillo and Zacatecas. Catalogued singleton rare entries are not an annual unbroken run, and no market premium is assigned here.
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.
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.
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.
The reference designated World Gold and eight matching normal mint types agree on 8.4600 g/.875 gold/.2380 reference AGW. The union of actual annual rows supports 1870–1884, 1886–1895, 1897–1898, 1900–1905. No 1885, 1896 or 1899 annual entry is established by those tables. The exact five-peso reverse is a radiant cap above scales, distinct from the one/2.5-peso half-wreath designs. Diameter and edge attribution remain unverified; neither is guessed. All three actual the reference five-peso search pages and the eight normal type records were inspected; copper pattern KM-Pn131 is excluded. Selected rare rows and annual tables were retained separately. Prices and mintages were not copied.
