I was just reading an article about the proposed 25th anniversary Sacagewea dollar.

It is to be made out of solid gold.
The article reminded me that we have already been there and done that.
Most of the coins were melted but twelve of the best looking examples were saved for posterity.

The original solid gold dollar is missing from the catologue.
