Lionel Messi’s jerseys from Argentina’s World Cup run will be auctioned in December, with a possible $10 million value.

If the jerseys do fetch above $10 million, it could make the sale the most valuable collection of sports memorabilia ever auctioned off.

The most expensive individual jersey ever sold at auction was one that basketball legend Michael Jordan wore during his NBA finals run with the Chicago Bulls in 1998. It sold for $10.1 million last year.

The shirts are being brought to auction by US tech startup AC Momento, which helps athletes manage memorabilia collections.

A portion of the proceeds will be donated to the UNICAS Project, an initiative with a Barcelona children’s hospital that helps kids with rare diseases.

The jerseys will be available for free public viewing when they are up for auction, from November 30 to December 14.
