There are tons of these in variant forms, all the same figures with different paint jobs and they have spread to other lines of figures. I have seen them anywhere from $5 - $100+ each, depending on the line they are associated with.
EDIT:
The following is from member Rocklord, who has not been on in several years. Unfortunately, he deleted his photos of them.
"Here's the Mannix Wrestling figures. I have 25 different ones but there could be more. They were released under the names IWC (International Wrestling Champions), International Wrestling, and Wrestling Champions. This was a big pain to put this list together. A big thanks goes out to Meatybat for helping me figure out all the variants.
