By simple water do you mean soak,run,or spray? Do you use your fingers at all? I'm new to this just started digging in february, and this is my first silver since i got a new machine monday. These were found in a honeysuckle jungle i was lucky enough to stumble into a month ago. Previous finds from the site with my old machine were a 1945 10k class ring, and 7 other silvers including 3 Spanish Coins, a 2 reales 1786, a real 1793 and a 2 reales cut in half dateless. Also a flat button with an eagle that I have discovered is a rare early diplomatic button. Needless to say I'm obsessed with the hobby. With this luck I may change my name.
