Miami, May 16 (RHC)-- The gun George Zimmerman used to kill 17-year-old Trayvon Martin has been re-listed for auction after the original listing appeared to be hijacked by fake accounts posting astronomically high bids.

Zimmerman has confirmed that the new listing with the United Gun Group is legitimate.  The starting bid is $100,000 with a $500,000 "Buy Now" price.

The listing is titled "George Zimmerman's Gun used 2/26/12."  The date is the day Martin died after he was fatally shot by Zimmerman in Sanford, Florida, while Zimmerman was volunteering for a neighborhood watch program.

The introduction for the listing, presumably written by Zimmerman, says the gun has recently been returned to him by the Department of Justice. The Kel-Tec brand 9-millimeter pistol is fully-functional and has Zimmerman's case number written in silver permanent marker, Zimmerman wrote, calling the gun a "piece of American history."

Zimmerman claims many have expressed interest in owning and displaying the gun, including the Smithsonian Museum in Washington, D.C. The museum quickly denied his claim, tweeting on Thursday it "never expressed interest" in collecting the firearm.

The 32-year-old, who was acquitted of second-degree murder and manslaughter in the summer of 2013, says that the proceeds will go toward "the demise" of the career of Angela Corey, the prosecutor assigned to Zimmerman's case, and to combat Hillary Clinton's anti-firearm campaign rhetoric.
