SAN FRANCISCO -- Seemingly always hanging out of his mouth during games, Stephen Curry's mouthguard turned into a speedy projectile during Game 6 of the NBA Finals when the usually even-tempered Warriors guard threw it in disgust after fouling out. Curry was immediately ejected from the game and was fined for his actions as his mouthguard hit a courtside fan.

Interestingly enough, two months later, one of Curry's game-used mouthguards was sold at auction for over $3,000. All in all, this may be one of the most unsanitary collectible items a fan could own. Even Curry is mystified at why someone would pay that much money for his used mouthguard.

"Whoever found it, sold it on eBay for an absurd amount of money," Curry said during a Q&A at a private fundraiser for Nothing but Nets, a grassroots campaign that works to stop the spread of malaria in Africa. "For some silicon. I don't understand why."

Curry was referring to the mouthguard he threw in Game 6, which he said he never got back. But the mouthguard that was sold at auction (not eBay as Curry said) was reportedly from a game in December not the Finals. So apparently someone out there still has Curry's now infamous Game 6 mouthguard. Which, again, is kind of gross.

Either way, Curry disputes that the mouthguard that was sold in August is even his.

"I don't know where that certificate of authenticity came from," Curry joked.

The sold mouthguard did have his name on it and came in a carrying case but it did not come with an actual certificate of authenticity, which perhaps means someone out there paid over $3,000 for a mouthguard that could be a fake. At least that's what Curry thinks is in the realm of possibility.

Some fans are truly fanatics.
