I thought that the readers of Mint Error News would like to see this coin. I have an 1884 20 Kroner gold coin that is double struck.
It has been authenticated by ANACS and is graded MS64. It is quite spectacular. As you can see it rotated between strikes and has the nose, mustache and eye from the first strike in the neck of the second strike.
This is the only mint error on a Gold coin that Iíve handled. It is for sale, please e-mail me if you are interested.
