Garbage Pail Kids Cards: $3,600
I honestly don’t know anyone who was a fan of the Garbage Pail Kids, let alone someone who was interested enough to keep the collectible cards, but there is a market for anything. They first appeared in 1985 and were created to mock the Cabbage Patch Kids, those frightening dolls with round heads that were popular in the 1980s. They have something of a cult following, and despite the fact that their merchandise does not have the widespread appeal that Cabbage Patch Kids merchandise does, they continue to command high prices. Their scarcity is advantageous. While a single Garbage Pail Kids card might cost as little as $300, a complete series of cards can cost as much as $3,600.
Comic Books: $15,000
There are a variety of valuable comic books available, and Action Comics No. 1 is only one of them. Some of the most valuable ones date back to the Golden Age, which spans the years 1938 to 1956. Comic books such as Batman #1, which was the first solo comic featuring Batman, are worth a minimum of $15,000 and have sold for as much as $2.2 million in the past. Comics don’t have to be ancient to be valuable, and they don’t have to be rare to be valuable. The Amazing Spider-Man #667 (Gabriele Dell’Otto Variant) from 1999 is a relatively uncommon comic book, and it is only sometimes available for purchase. When they have been sold, the highest price received was $20,000.
