What to do with bent, corroded, otherwise unspendable coins?

My stack of bad coins. Counted 68 quarters, found metal detecting the last several years.

I soak my clad in a vinegar salt mix to get any crud off. I'll roll pennies. The nickels, dimes, and quarters I dump into vending machines then hit the refund button for shiny replacements. I dont let my tarnished clad build up so it's easier to get rid off. I'll put any bent coins (I don't find many) into tip jars.

I use mine for car wash and coffee, bent or dirty don’t matter.

You could sprinkle them around your metal detecting competitions yard.

Reload them spent .12 gauge rounds with a stack of crusty Zincolns. Go to the range and watch the magic...(just don't use your best shotgun...) LOL! Sub.

I put my bent coins in my vice, and flatten them out. I always tumble my coins at the end of the year, and take them to the bank to cash in. Then I run to the coin store, and repurchase silver bars, or junk silver coins. Every now and then, the teller at the bank will bring a coin back to me that she said would not go thru the machine. It's not often though. Clean those babies up and happy spending !
