A listing on bidding site eBay for a microphone purportedly thrown by Cardi B at a fan has reached $99,900.
TMZ reports that the seller, Scott Fisher, works for a company that provides audio kit for Las Vegas clubs.
The entertainment outlet reported Fisher as saying the proceeds from the sale, which ends Tuesday, would be split between two charities — the Wounded Warrior Project and Friendship Circle Las Vegas, which helps teens and young adults with special needs.
The mic-hurl episode was the latest involving performers being the target of objects from the audience.
In June a man threw a phone at Bebe Rexha during a concert in New York, landing the singer in hospital.
The same month an audience member threw a bag purportedly containing the ashes of their mother at the stage while singer Pink was performing in London.
And last year Harry Styles good-naturedly paused a New York concert after someone threw a chicken nugget in his direction.
In December, Guns N’ Roses frontman Axl Rose pledged to stop throwing his microphone into the audience at the end of a show after a fan was reportedly hurt in Australia.
