Mexican silver marks
Mexican silver marks are identifying inscriptions found on Mexican jewellery items, useful to collectors to identify a piece’s appeal or value.
Mexican silver marks can be traced back to circa 1900, continuing throughout the century.
Key marks include the "Mexico Silver" or "Silver Made in Mexico" marks that are seen on pieces from the 1920s through mid 1940s. Their silver standard varies, but is commonly above .925 purity.
Marks indicate silver purity in a percentage of 1000ths. An intaglio "900" mark is found on work dating from circa 1900 until the 1920s.
Pieces from the mid-1930s to the mid 1940s generally have the intaglio marks "980, 960, 940 & 925".
The incuse mark "970" was the favorite standard of Antonio Pineda, the legendary Mexican modernist jewelry designer. Most work from circa 1950 or afterwards is stamped "Sterling" or with an incuse "925" stamp.
“Eagle” marks were instituted by the Mexican government in 1948, with the first example used until circa 1955. A silhouetted example was then favoured until the late 1960s or early 1970s.
Features of the Eagle include on its chest, which indicated either the city of original or an individual jewellery maker. For instance these include, among other variations:
- Eagle stamp #1 was for Mexico City
- Stamp #3 was for Taxco
- Stamp #16 was registered to Margot
The Eagle system was discontinued around 1979, replaced with a new lettering and numbering system.
