I wasn't implying that that set had appeared, only that more than one set had been officially commissioned - sorry for any confusion.
Isn't it nice that all of us our free to collect what we will? If you don't like coins made by the mint in questionable circumstances, you don't have to collect them. I think it's clear the mint director picked the 1804 date because it was the last year dollars were minted, and he wasn't there to know they used the prior year's dies.
Another thing that points to them being a scam is that several of the Class III coins also came with affidavits from high mint officials that they were original genuine specimens struck in the year 1804, yet they were coins that these same officials were involved with restriking. Another interesting fact is tha with the exception of the Linderman coin, all of the other Class III dollars trace their pedigrees back to the hands of William Idler and his Son-In-Law Capt Haseltine. While the Muscat of Oman set never came to market intact, the coins from the set did come to light in I think it was the Waters collection. It contained an original 1804, the proof 1804 eagle and several of the 1834 proof coins. No holder of course and no stated previous pedigree, but where else would these coins have come from?
