2023-P Kennedy Half / #2 / New DDR

So....after trying to look for matching markers for well over a half an hour, I decided to look closer at the doubling itself on this coin and the previous 2023-P I posted.
Should have done that first!
Decided it certainly looks, to me, like a different unlisted DDR than the other!
Doubling on the snake and on the stars is different.
Is V.V. the only place for attributions of halves right now? I tried looking at Coneca, but see very few pictures. Or do you need to be a member to see the pics? Thanks!
