# Professor's Letter #123/146 — XY

## Summary

Professor's Letter was a staple Item of the XY standard format, fetching basic Energy to smooth a deck's setup, so it saw heavy play in competitive lists. Uncommon and constantly reprinted, it has always been a player's card, with 5ban Graphics credited as illustrator and little collector chase. A $0.31 modelled guide, up 3% over 30 days on 9 copies traded, says bulk, with 121 days of inventory on the board, and the economics stop there: a PSA 10 guides at $34, 111 times raw, but PSA does not split this card’s population by finish, so no gem rate can be read for it.
