As a major history buff, I've always been fascinated by Bonnie and Clyde.

Their unique story of crime and romance made them more than just bandits, and the media sentimentalization in the 20th century agreed.

Authorities were vigorously on the hunt for the couple, including Dallas County Sheriff Richard "Smoot" Schmid, who's remembered as an officer who "came this close to nabbing Bonnie and Clyde."

Years later, a pair of Houston sisters discovered their grandfather had not only been involved in the infamous case, but had secretly stashed away relics belonging to the gangsters.

Schmid's granddaughters Diana Knowlton and Debbie Daily were cleaning out their late grandfather's home when they came across a small black box.

"We poured it out on the floor and sat around, going through the jewelry," Knowlton explained. "I opened it up and it was Bonnie Parker's ring!"

Bonnie Parker's ring featured three snakes, encrusted with one jewel each.

"That's the first we had ever seen or heard anything about the ring," Knowlton said.

While Schmid passed away in 1963, he had grabbed the ring from Bonnie and Clyde's car following the fatal shootout, but didn't tell a single soul.

Other items related to couple included mug shots, arrest warrants and a four-page letter to fellow gang member Raymond Hamilton, penned by Bonnie and signed by Clyde.

After contemplating what to do with these artifacts, they decided to contact Bobby Livingston, vice president of R&R Auctions.

After examining the ring, Livingston said the jewelry piece may be the closest thing Bonnie had to a wedding ring.

"If Clyde gave that ring to Bonnie Parker, then it is the closest thing there is to a wedding ring between Bonnie and Clyde," Livingston said on the latest episode of Strange Inheritance with Jamie Colby.

Contrary to popular belief, Bonnie and Clyde never married, as the former was married to another man before she met her bank robbing partner.

The sisters decided to sell their newly discovered memorabilia in order for the pieces to truly appreciate.

"We thought the items would be better off in the hands of a collector, someone who will truly appreciate them," Knowlton said.

In the end, the Bonnie and Clyde collection sold for $100,000, with $20,000 coming from the purchase of the ring.
