The bottom one has got to be 1800s. The middle one quite possibly 1800s as well, but it looks to me like its a little younger than the one at the bottom. If not 1800s very early 1900s. (I seem to remember seeing other tokens like that that were made in the 1890s or so, same basic design but with different names and denominations and so forth.) The thing at top is some sort of tag. Maybe a miner's tag? But I cant remember seeing any old miners tags with that kind of hole. Theyre usually round. Dassel could be the surname of a German employee? 1879 appears to be the date. If you found the tokens near that tag thats an excellent way to date them. Really cool finds. And did you find these in Illinois?
