Anyway, I have purchased this pair of Mexican sterling silver earrings. The stamp says `Mexicco`, `925` and `TU-D4 (or 04, I'm not sure)`. I know the basics about silver hallmarks and I've been collecting silver jewelry and coins for some time, so I know the general idea. I would like to know the date, city or any information you can give me about these, thank you :)
PS: Sorry if the images are too big...
