Finally had some time to go through the final reject can in my multi-sort process. As you can imagine, there were some really unattractive coins in that container. So while I'm hand-sorting the rejects of the rejects, I thought I saw the back of an Indian Head. It was pretty encrusted. I couldn't make out the front--it looked more like a flying bird than a human head. The eagle-eyed missus read the date: 1857! Woot! I'm glad I've invested so much time working on cleaning processes.
Will post pics later.
