Made in Mexico Mexican Sterling Silver 16" Link Necklace

Dating to anywhere from the 1970s to 1990s, may I offer this Sterling Silver (hallmarked as pictured) round link necklace that was made in Mexico. While the reverse of the necklace is plain, the front of each medallion bears an interesting geometric design. Length of the piece is 16" and width of the links is 5/8". Weight is 28 grams. Tongue in slide clasp clsoure. Very nice condition with no problems I can spot save for a few bits of polish residue that have found their way into the nooks and crannies - a light wash with take care of this.
