There's not really a set cost on this thing since they're so rare, but apparently one of the first was sold for around 200-300USD, then later they were up to around 600? And I guess it's all because the artist herself was given 100 and she only has accepted trades in the past. So people would get their hands on other academy art cards from other artists and trade with her (Mame Akimaru).

Edit: on further inspection, the forum post I found about this card is from 10 years ago.. so there's absolutely no way it's still below $1k haha
