Even though this card number was issued as an "A" version, there were no further cards created under the number 351.
Hank Chien card #351A is one of the rarer cards in the Walter Day Collection.
The world-famous Kong Off (the official Donkey Kong World Championships), created by Richie Knucklez and Billy Mitchell, authorized the Walter Day Collection to create a a limited edition series of trading cards that honored the 12 main players competing in the 2012 event at the 1-Up in Denver, Colorado.
Only 117 copies of each card were printed. The cards received hand-written registration numbers on the lower backside of the cards. All 12 players autographed 22 copies of their own trading card. Each player received a full set of all 12 autographed trading cards. Except for a few existing cards, all the remaining cards were lost when ownership of the card series was transferred over to the Walter Day Collection in early 2014.
