A copy of an apparently experimental 1910 Satin Proof that had Treasury Secretary Woodin's input is on auction over at HA. It's SP-66+ and if the comps are real, could go for 7-figures.
The writeup for the coin has some excerpts from Roger's book, but the rest is apparently brand new; maybe Roger assisted in the write-up. This coin is called "Newly Discovered" but either this type of coin was not known or they knew that an example or two were out there but they didn't know who had them.
The references are to the two 1921 Special Proofs. This coin is apparently not Satin (Roman Gold) or Matte, of which these 1910 Proofs were known (Matte pop was one, this is a different coin apparently).
Very interesting write-up, click and read. Registerd at both PCGS and NGC, but the population = 1. Bidding is already at $105,000.
