There was a guy on Ebay selling 52-57 xmas rack packs. Looked and sounded real. He had one that he wasn't selling but he had pictured on his "About Me" page with the Mathews RC on top. Also claimed the folks he bought them from had the Mantle RC on top but held onto that one. He was getting tremendous prices for them. wynnian was his user name, you can look at his feedback and see what he has sold. Incredible.
Here's one with Pafko on back and his story on these rack packs:
