Sorry for just now responding CP, but I've been out of town attending a funeral. That was an absolutely incredible day you had! You may only run across 2-3 sites like this in your lifetime so I know this must be a big rush for you. Those are exactly the sites I strive to find with my research, but they're hard to locate. Sometimes you just have to get lucky. I'm glad someone was able to ID your cut tree coin. Hopefully you can get it straightened out. I flattened some of my bent hammered using the "hot oil method" that I outlined in one of my articles. If you're interested in that PM me your email address and I'll shoot you a copy of the 2009 article. With the quantity of finds that keeps coming from this site it appears you have a long way to go, and I'm sure more early silver will be discovered. Have fun with it, and don't forget to look for those trash pits which are sure to be lucrative.
