Vintage X3 925 MEXICO Bangles

I have a set of 3 925, hand crafted, collectible, bangle bracelets that are hallmarked "925 MEXICO" & each is signed differently. The one with the floral pattern says "TB-77", the tribal diamond patterned one says "TA-30" as far as I can tell, the striped one says "TC-89" which is a more common Hallmark in Mexican silver jewelry. The name of the specific artisan who's initial and number are stamped here was lost due to bad record keeping but the presence of this Hallmark guarantees the sterling standard. The "T" in each Hallmark represents the city where they were made, Taxco. The second letter, next to the "Ts" are the last initials of the artisans who crafted the piece, and the numbers are the registration numbers given to the silversmiths by their local assay office. These were most likely crafted in the late 70s or early 80s. All prices are negotiable! All sales are final!
