Part of a 22-card set that was, according to conventional wisdom, never intended to be released by Topps, the 1968 Test basketball issue is quite rare and highly desirable today.  In 1968, Topps had no license to produce NBA cards, though the existence of this issue serves as evidence that they were at least considering it.  In the early 1990s, cards from the issue began to surface in the hobby, and just over 200 cards have been graded by PSA.  This example, picturing Hall of Famer Hal Greer, would be just his second card, an extremely high-grade specimen that is severely off-center, enough to earn a MC qualifier from PSA to go with its NM-MT 8 grade.  With just 11 examples graded by PSA, however, finding a better-centered example might be a challenge.
