I had dirty clad piling up and dug out my cheesy tumbler to clean it up. Out of boredom I threw a few oddball items in, like the weird dirty metal glob that had a milled edge I found early this year and had kind of forgotten about. To my surprise it came out with a pretty nice shine and I can make out a few letters from "QUARTER" so guess I found a melted Washington. Could have probably figured that out at the time if I'd given it a little thought.
