We used to call then aluminum coins, play coins. We had a chicken on it and it said henny penny lol Kids used to play with them 1's, 5's and 10's, I believe. The Swastika was a good luck symbol and I think it went way back (like Egyptian times?) Later, it was twisted the other way and turned into the German symbol everyone is familiar with. I've found a couple of good luck tokens with it. Nice stove token. I think tokens are a lot of fun to get. They all tell a very precise story and give you lots of information, so you can research something you may never have heard of. Great piece. I hope it cleans up good.
