I don’t like to beat a dead horse, but you literally said that unrealized gains wouldn’t benefit you at all…
I understand your point of view and that you have too spend more money for the same cards now, and was just trying to validate the other side, that you may have a surplus of certain cards in your collection, that will be traded or sold for something else you rather have. And proportionally those are worth more now compared to what you wanted to get before.
I wouldn’t know for sure, but I’m guessing PSA 10 1st Base Blastoise never reached half the charizard price before.

Anyway, good luck with the trade
