Kids have always loved variety packs of cereals, and the Post Ten Variety Pack Cereal Pack from 1962 is no exception. Post Cereal always issued standard-size, large cereal boxes, but it changed things up in 1962, issuing single-serving boxes called “Post Tens.” The little boxes were situated in cardboard trays.

The boxes could be cut open and used as cereal bowls. The Post Tens tray was a platform for the boxes, and it had three 1962 baseball cards on the bottom: #131 Willie McCovey, #75 Rocky Bridges, and #5 Mickey Mantle. Complete Post Tens trays are very, very rare, which is why they sell for so much when someone does get their hands on one.
