I got a good jar of marbles 20ish years ago at a flea market in Michigan City in Indiana. The Seller told me they were in a coffee can and covered with rust. She rinsed them in toilet bowl clearer. From what I could see they looked good. Lots of Pelts and Akros. Dumped the jar and started sorting. What I found made me cry. It ate up a specific type of glass. This one of my good Bloody Marys🔥
