I know this is a

dead topic but I came across this as I was looking for similar info on a 1964-D 25¢
DDO just now.
Ok, I don't consider myself a professional numismatist however, I'm pretty sure I know how to interpret the various variety listings from the main attribution catalogues (Wexler Files, CPG, Variety Vista, etc.) but then again maybe I don't.....
But since the OP's coin obviously appears to be a business strike, wouldn't that limit the possibilities to 1964 25¢ WDDO- 003, 006 or 008 since all the rest have been designated as proofs?
