How Much Is The Amazing Spider-Man #66 (Feb) Worth?

The Amazing Spider-Man #66 (February 1969) is a classic Marvel Bronze Age book. Based on our own sales records here at ComicBooks.com, recent realized prices range from $60–$133 for raw copies, with a CGC 6 selling for $180 and a CGC 9 fetching $428. A high-grade CGC 9.8 has an FMV estimate of around $2,873, while a CGC 6 is roughly $140 and lower grades can be as little as $20. You can see the full grade ladder and complete sales history on its page here at ComicBooks.com. Note: I'm not finding a specific Wolverine 30th Anniversary insert tied to this issue in our records — it's possible you have a promotional item or insert tucked inside the comic, which wouldn't typically affect the book's value on its own.
