You'd never be able to afford it. Never underestimate the internet and simps with lots of disposable income.
On a more serious note, these movie prop auctions always see massive spikes towards the end. A while back there was an auction of Farscape props - like Emperor Stalik's full costume including the prosthetics, cast costumes for all the major characters, etc. Prices seemed affordable until like the final days, then the prices jumped like 5-10x at minimum. Same for The Expanse. Some shit had opening bids around $500-1000 and by the time it ended some was 20k+
Even the crappy generic props will end up 2x start at least
