Before putting into a tumbler, however, you might just try taking a few of them and putting them into a plastic cup with soapy water. If you let the water just sit for 12-24 hours, quite a bit might come off just while sitting there in the soapy water. I haven't done it with silver halves, but have quite a bit with pennies through quarters. It doesn't always work, but works well enough so that I keep doing it (especially with gunky, sticky coins).

NOTE: ANY stocks I discuss, no matter how compelling, carry risk- often
substantial. If not prepared to buy it multiple times in modest amounts without going overboard (assuming nothing really wrong with the company), you need to learn more about the market and managing risk. Also, please research covered calls (options) and selling short as well.
