Joe DiMaggio Rookie Card
Wikisimpsons - The Simpsons Wiki
The Joe DiMaggio Rookie Card is an old baseball card, and presumably very valuable. When all the workers at the Springfield Nuclear Power Plant get given a $5 voucher as a Christmas gift from Mr. Burns, Mr. Burns gives Homer the old rookie card. Homer takes it to Android's Dungeon & Baseball Card Shop to get money for Christmas, when suddenly the Comic Book Guy offers Homer all the money in his cashier in exchange for the card.
Trivia
- The card is a possible reference to John DiMaggio.
