Bob Barker’s final episode of The Price is Right is this morning. After 35 years, he will be announcing his final “come on down.” For those who would like a piece of history from the show, one of Bob Barker’s microphones is being auctioned off on eBay. The microphone will also come along with a letter of authenticity written and signed by Bob Barker. 100% of the proceeds will go to United Activists for Animal Rights. Currently, the highest bid is almost $20,000. The auction ends today at 7:43pm PT. Can you guess what is the right price?
