That's interesting. I myself have never tried tumbling rocks or anything else. I have tried reading up on it in the past to find out what to use for polishing media and such. But never was interested enough to figure it all out.
I figure that a large version of a small rock tumbler should work. I have thick rubber mud flaps and floor runners for the side holes and plenty of rollers and gear reduction units from old grocery store counters with the moving rubber mats.
When I parted out three of those I found some coins in the bottoms of them. A few silver ones, but mostly dirty sticky spending change. I find coins and such in many things I end up with. Old women's purses can have rings, coins and unused postage stamps hidden within them. I have found money in clothing in the past. The best find was a bunch of 1976 2 dollar bills. It was about $80.00 or so worth of them from what I remember. They had been washed so they were not collectable in my opinion even tho they were all in series. I remember when I was paying for some gas with some after I had found them that a guy wanted all of them that I still had. Didn't matter to me as I was just going to spend them anyway. I noticed as the years went by that I found less money and not as often in jeans, jackets and other clothes that I would look through before storing the good and ragging the rest.
I thank you for your input and reply.
