George Zimmerman is auctioning off the gun he used to kill Trayvon Martin in February 2012. In his auction listing, Zimmerman calls the gun "a piece of American History," but not all the bidders are approaching it with the same reverence.

Early Friday morning, the highest bidder was someone who used the name "Racist McShootFace" and offered to pay $65 million for the Kel-Tec PF-9 9mm handgun. The "Racist McShootFace" account has since been disabled, according to Gawker, but other bidders have picked up where "Racist McShootFace" left off, and continued to place massive bids on the gun.

Zimmerman's original auction was listed on the site gunbroker.com, but after that auction was taken down, the gun was listed on unitedgungroup.com. The company that runs that site is denying responsibility for the listing.

After the "Racist McShootFace" account was suspended, a user named Brez Morrell led the auction with a bid of $485,000, according to Gawker. "I hope your children get murdered," Morrell said in a comment left on the listing.

Another apparent troll named Quincy Lohan commented, "I can't own or bid because of my numerous felonies defending myself, but I'm single if the winning bidder cares."

United Gun Group did not immediately return Complex's request for comment.
