Mexican Silver Jewelry Hallmarks and Information
Prior to 1948, pieces were simply stamped. In 1948, the Mexican government began the use of the Eagle stamp. A specific number associated with a silver manufacturing company or designer was stamped within an Eagle stamp.
1900 - 1948: no eagle mark
1948 - 1980: eagle mark
1980 - present : letter/number system
Be aware also, that smaller pieces of jewelry MAY NOT have an Eagle mark due to lack of room so the Eagle would then be stamped on a hang tag that was attached to the jewelry which most times will be removed by the buyer.
After 1979 Registry marks were required i.e. TS-24...TAXCO which is a registration system which combines letters and numbers.
The first letter represents location. The second letter is the first letter of the maker's first or last name. The number represents the order in which the maker registered his mark.
T represents Taxco, Mexico. S is the first letter of the maker's first or last name. 24 shows that this maker was the 24th individual to register under the letter combination of "TS".*
