So, I had this 1904 Indian-head that I dug up last weekend. I figured, "Hey, 1904, it's probably in the good range, so no economic loss here." I rigged up a DIY electrolysis system, and it seemed to work at first, but the coin itself wasn't really bubbling, though the alligator clip attatched to it was, or at least right where it connected to the coin there was lots of bubbling. The water was getting dirty, but after 10 minutes, not much had some off, so I threw it in a dish with apple cider vinegar. And that was the end of that chapter. It's not a slug yet, but it isn't pretty...
