Yeah, that was fun. The reason I checked the date was to verify on an AG coin where the spit was worn off that the date matched the VAM 3 so that I could feel better about the remaining reverse markers. Not only didn't it match VAM 3, it didn't match any listed 91-CC VAM. John Roberts and I spent an hour or so poring over Heritage lots looking for more far dates. The irony is that currently 91-CC VAM 7 is pretty much a "one and done," but looking at the obverse. The OP coin has the VAM 5/6/10 reverse.
Oh I haven't submitted it in to NGC yet. But I like to ask these questions well in advance to see if there's any doubt if I shouldn't or not. Which reminds me to update the GTG threads on here lol.
