Most of the jerseys display the number 26, in memory of the 20 children and six educators who were killed at the Sandy Hook Elementary school on Dec. 14.
Money raised in the auction will fund a scholarship in memory of Rachel D'Avino, a teacher's aide who was among those killed. She was a cousin of a former Quinnipiac soccer captain, Lauren Carmody-Grenier.
The online auction has so far raised more than $10,000. Items still on the block include a Barcelona jersey signed by the entire team and another from Argentina's national team signed by superstar Lionel Messi.
