We will probably see a D mint proof ASE before too much longer, they've had P, S, and W. They could probably hype the first D Prof ASE pretty well and sell a bundle of them.
Something else that I want and cannot afford. Too much going on at the mint for me to buy everything I want. With that said, DO IT!
To date, I think the only proof coin that has been minted at Denver (mint) is the 1984 commemorative $10 gold............
There was a 1907-D Proof Liberty Double Eagle, but only one coin was struck. I know of no other Denver Proofs.
Heck they missed the boat, if they wanted to mint a 100th anniversary coin of some sort. Im actually surprised that they didnt think up some sort of fantasy gimmick commem. Oh wait, someones already cornered the market on all that horse crap
2031 would be a good year, 125th anniversary of the Denver Mint, or 2036 the 50th anniversary of the ASE. Not sure how to get it closer unless you want mark the 40th Anniversary in 2026.
