I would not bid on this auction after reading the description and looking at the picture. They don't quite marry up. The coin as he calls it is a German pin with a trout on it not a bass. Is nowhere near to being a coin, I have a similar one from when I was stationed in Germany. http://page.auctions.shopping.yahoo.com/auction/69301971
Well, that is a pretty fish, and like the background, but no, this is not something that I would buy either. Guess the Seller just didn't know what it was - probably should have called them tokens or something.
Note for neptune Hi, You can get the same effect using the paint from stained glass art kits sold at walmart. I used to polish Indianhead nickles and background them that way for jewelry.
