PLEASE ASK ALL QUESTIONS AND SETTLE ANY ISSUES THAT YOU MAY HAVE BEFORE PURCHASING OR MAKING AN OFFER - GOOD COMMUNICATION MAKES GOOD FRIENDS AND A SMOOTH TRANSACTION! This is an offering of a GLASS CONTAINER/VIAL OF????? HONESTLY!!!.... I'm not sure what the heck it is! It's a glass vial with what appears to be a "silvery" SPLINTERED metal; with a wax seal. Hard to see, but the the front of the vial is etched with a crossed hammer logo - which is a universal logo for mines or miners or mining, with the date "1936," and the name "PACHUCA." Google research indicates that Pachuca, Mexico is "...famed Pachuca silver-gold mining district where approximately 1.4 billion ounces of silver and over 7.0 million ounces of gold were produced, making it one of the largest historic silver-gold districts in the world." That having been said, I believe this to be possibly a "sample/souvenir" of one of the local mines. Or maybe a specially prepared product for??? Dentistry? Medical? Jewelry industry? Your guess is as good as mine or better if you know what it really is :-) and if you do, please let me know!
