I received these coins in slip in plastic holders. In order to better display them I placed them in the only coin holder I had at the time, one for U S gold coins. You will note there a small red stains on some of the coins and first thought was how come? So I went on line and did some research. This happens when the dies are not clean and advises not to try and remove the stains. It does not mean that the gold is impure. You can confirm this by going on line.
