Does it actually sell for that amount, or is that just an algorithmic phantom price caused by interest but no actual copies of the book?
I always thought those absurdly high prices for out-of-print books were just the result of a cascade of pricing bots saying, “hey, we don’t have one of these, but if someone is willing to pay, we’ll buy the second-hand copy that these other guys are selling and send it along at a profit”.
