Sometimes, you'll find more than just spare change and pens between car seats.
According to The El Paso Times, one Sacramento couple discovered a 1961 wedding ring stuck between the seats of a car they'd purchased in January.
Shannon Callahan was digging around in the back seat of her 2004 Grand Am last week, searching for her husband Steve's missing cell phone, when she felt the 15-carat gold band.
"It was wedged in there pretty good so I reached in there again and moved the seat forward and back and found the wedding ring," she told the newspaper.
The Callahans want to return the ring, but so far they haven't been able to locate the car's previous owner.
"I would really like to return the ring," Shannon said. "It's not like it's just a lost set of keys. It's a token of somebody's love, it's a milestone in a couple's life."
The Callahans aren't the first to have found a ring in an unlikely place. In January, a woman found her engagement ring in the toilet more than 35 years after it had slipped off her finger. Another couple even found a lost wedding ring in their dog's stomach.
