The Topps ’93-94 No. 23 card (Jordan dunking) was printed with two different backs. The incorrect back reads No. “64” and the correct back reads No. “23.” The No. 64 back actually belongs to the Michael Jordan 50 point club card pictured all the way to the right. For those of you that don’t believe me check out the less than professional video that I made (at the end of the post) to prove the error. Also, the No. 23 card incorrectly states Michael Jordan’s birth date as “4-3-68.” His actual birth date is 2-17-63.
