If you collect coins, doing this will damage their collector's value. If you're doing it for decoration, or for cleaning parts that are needed to restore machine function, it can add or at least retain value. It's a great build, but the value of it depends on what you're doing with it!

I first got a tumbler to grind found pebbles and broken bits of rock and glass into "gemstones." They can also be used to clean and polish metal parts, jewelry findings, and reloadable brass for cartridges. And that list is not all-inclusive!
