5 Times When "Pawn Stars" Were Caught Cheating Their Customers

#1 A seller with a 450 year old book on alchemy walked into Gold & Silver Pawn

After a call to his rare book expert, Old Man finds out the book is worth $20,000. That's when Bob amazingly accepts the low offer of $7,000 after Old Man says "You know if I give you seven for it, I won't have money for dinner tonight." Yeah, sure.

#2 15th century Samurai sword that could potentially have brought the shop over $10,000.

They ended up agreeing on $1,500 which was a modest price. An expert later determined that it was actually worth $5,000 to $6,000 in its current condition, but if it was restored for $3,000, it could sell for as much as $15,000.

#3 1890s Colt .45 Peacemaker Revolver

The pair eventually agree on a price of $3,000 before Rick consults his weapons expert.

After consulting with his weapons expert, Rick learns the gun is worth $5,000 in its current condition.

Many guns manufactured during this time range from $2,000 in value to $42,000, so while it was within market value, Brian made the low range on his sale, which meant a win for the Pawn Stars.

#4 Old Man pitched an offer to him for his 1951 signed baseball of the World Series Champions.

In 2017 a baseball was sold, but it also included the future wife of Joe DiMaggio, Marilyn Monroe's signature. That ball went for $15,000 on Antiques Roadshow. Even without scarlet's signature, Clint's ball was estimated to have a worth of between $5,000-$7,000.

#5 Diane had a copy of The Godfather screenplay signed by Al Pacino.

After Rick's handwriting expert confirms it was indeed the actor's signature, he offers the seller $500 for the leather-bound book, thinking that it would only generate $1,000 at auction.

Diane, doesn't counter, and instead responds with, "now that we know it's Al Pacino's signature, a fundraiser would probably net more money than that."

And she was right.

She ended up selling the screenplay that was donated along with "thousands of other books" for $12,000.
