Mastro offered these fifteen 1953 Topps Unopened Five-Cent Wax Packs in his April 2004 auction, which included the OPC archives.
Global Authentication graded and encapsulated all the packs, and the breakdown was as follows: GAI EX+ 5.5: 7 packs; GAI EX 5: 8 packs.
I don’t know what the lot sold for, but there was a separate lot with just a single pack, and it sold for ~$12k.
And in case you were curious, here’s what a 1953 Topps 24-count 5-cent wax book looks like.
