In all, 105 bids were placed on the mask, which is said to be one of nine masks created by a sculptor for use in a Casey Anthony parody video.
It's hard to tell whether the seller, "prophunter," will see his near-$1 million, since 16 bids were either retracted or cancelled during the course of the three-day auction, most claiming they entered the wrong dollar amount on their bids.
The guy selling the mask somewhat agreed with that statement.
"Forget Freddy, Jason, Meyers, here's your chance to scare the *#&% out of everyone and win every costume contest with this amazing Tot Mom latex rubber mask, possibly the most frightening mask on the planet," the seller said.
Prophunter says the mask would fit most head sizes and ship for free to the continental United States to the winning bidder.
"No matter what your opinion of the trial is, this is still one heck of a conversation piece," the seller says. "I bet Nancy Grace would love one of these."
Yesterday morning, when the bidding was around $24,000, there were 108 bids placed on the mask, although there were just 105 bids when the auction ended just short of $1 million.
According to eBay, the winner bidder has around four days to pay up before they can start a resolution process. If they don't, eBay suggests you contact the Internet Crime Complaint Center or law enforcement in the bidder's area.
We're not sure if he's the seller of the mask, but our emails to a man named Scott Dunkel -- a movie prop and costume seller who goes by the name "prophunter" on several websites -- were not returned.
