Sellers go head to head with four shrewd dealers to sell their treasures for the best price. But there's a catch: pass on an offer and they can't go back. A king's solid gold swordhandle, NASCAR hoods, Babe's baseball and more.

The four dealers vie for Kurt Cobain's inscripted guitar and a lock of Elvis's hair. A Civil War enthusiast is sent packing. Negotiations heat up and sellers learn an expensive lesson: come prepared or get crushed.

The 4 dealers vie for a Marilyn Monroe dress worth half a million. They go buggy for a rare African insect collection, a Tiffany lamp, early photos by Ansel Adams, and a pink bunny that keeps going and going and going.

Our four dealers gamble on the craziest collection yet including a prohibition roulette wheel, a "T-Rex of the sea", a movie star's saddle, and a map that leads to murder. But it's a tiny bottle originally bought for 25 cents that drives bidding sky high.

The dealers wonder if there's money to be made on a car that walks on water. Rare Star Wars swag has Patrick moonstruck. And everyone scrambles to score some Blues Brothers bling. Someone goes home swimming in cash; others end up taking a bath.

The four dealers vie for a jewel worth half a million, a superhero suit worth $250K, a collection of love letters that fell out of the sky, and a collection of antique liquor. Someone's going to strike it rich; others will be sent packing.
