I agree with muddler, and to make a good counterfeit proof, one would need access to proof planchets and some high quality dies...
The only person I know of that could produce such a coin would be created by Daniel Carr of the Moonlight Mint, where he produces fantasy overstrikes (on a genuine Mint press he purchased from the Mint as scrap), like the 1964D Peace dollar. Since Daniel only strikes fantasy coins that have not been minted by the U.S.Mint, thay cannot be labeled as counterfeits..
A google search will show you his quality of work...
