These are some of the rarest books ever, and what makes them astounding, their condition grades very highly, with potential to be the best graded copies ever found.
The dealer who was contacted about these books was completely...astounded. They belonged to a lifelong collector who was 85 at the time of their revelation.
I collect comics and any single, pre 1939 professionally graded copy of Superman or Batman seen on that table is worth more than my near 7,000 collection combined. I need to go hide in a fucking closet lol.
Recently, copies of Action Comics #1 (first Superman) and Detective Comics #27 (first Batman) fetched over US$1 Million
each. The books above might grade higher and have the potential to go over 9.4 (out of 10...which ranks as Near Mint and practically unheard of with comics 70+ years old).
