Just how many copies of Hulk #181 are there?? Seems to be a limitless supply. There's a seller on eBay right now who, if you check his sold listings, has absolute tonnage of books like Hulk #181, Silver Surfer #'s 1 and 4, Spider-Man #'s 50, 129, 238 and 300, Avengers #57, Iron Man #1 etc and many more. I counted 24 sold copies of Hulk #181 and 14 of Silver Surfer #1 (1968) in just the three months going back to early June. He has more of each currently listed as well. And this guy has been selling these particular issues (and more) for many years now.
I won't name him, but there's definitely warehouse quantities at play here. It seems like an endless supply. Does this not concern anyone who's paying hundreds or thousands for these 'rare' books? Anyone else can check these sales as easily as I can..
