This 2010 Topps Baseball #661 Stephen Strasburg certified autograph is serially numbered #1/1 and was originally intended to serve as a highly desirable insert in the popular product. However, while the card is stamped #1/1 and the certified autograph is valid, this particular example was never released in pack form as Topps committed an error in its production. While the obverse displays all of the merits indicated, the reverse is what halted insertion. Beneath Strasburg's college statistics, a infinitesimal validation line reads "Topps Certified Autograph: This card is not valid without sticker: 301333". The authentication hologram attached to the card is numbered "301808" and does not match. For understandable reasons, the card was pulled and another copy was issued in its place. One of the more interesting modern inserts we have offered that grades in (NM to Mint) condition.
