Hand Autographed Cards from Lottery Redemption
These cards were only obtainable by submitted redepmtion stickers in the hopes of getting one of the cards. They are standard card stock, but have a "B" in the card number instead of an "A" like the foil signatures.
Note that set 1 has two expceptions - the cards for Ui and Sawako do not have gold or silver signatures, and their autographed cards are designated with "A". Very strange!
