Last week, Michael Jordan's 1986-87 Fleer rookie card sold for $150,000, and an unopened wax box of 1986-87 Fleer cards sold for $126,000 at Robert Edwards Auctions.

Hockey cards were produced in far fewer quantities than baseball in the mid-1960s. The 1966 Topps PSA population report lists 7,448 Mickey Mantles and just 687 Bobby Orrs in his mainstream issue.
