The FC Rockhounds Club president was gifted a bunch of rusty, mysterious old cans of rock grinding and polishing abrasives, and offered them to me if I picked them up. Here's the initial collection. Some were obvious and valuable, some mysterious, and one item actually a bit dangerous so I took it to hazardous waste disposal!

Later I shared some of the basic SiC coarse grit with a lot of club members.
