But somehow it fell out of her purse and onto Route 2 in Hermon as she drove to work.
Coincidentally, Stevens's next-door-neighbor, Kevin Peary, saw a flash of green fly off a car as he was driving home from work at the Orono Fire Department, where he is a firefighter.
''I thought it was trash coming off the vehicle," Peary said.
But when he stopped and realized it was a wad of cash, Peary called police. He waited for Sergeant Bill Laughlin of the Penobscot County Sheriff's Department to arrive before counting the money.
''I knew it was probably a couple thousand," Peary said.
Meanwhile, Stevens realized the cash was gone when she stopped for coffee in Bangor. She called her husband and then reported the money missing to police.
''I said, 'Nobody's going to turn that in,' " Stevens said.
Then on Friday morning, a Bangor police officer called Stevens to tell her about a story he had seen in that day's Bangor Daily News about money that had been turned in to Hermon police.
Stevens called Laughlin and described the money: $4,500 in $50 and $100 bills wrapped in a rubber band.
The sergeant said he knew he was talking to the rightful owner.
When Stevens met Laughlin and Peary at the Orono Fire Department on Friday to pick up the money, she and Peary hugged.
Then she gave Peary $500 as a reward.
''For me to give you $500 means a lot to me," Stevens said, choking up. ''I wish I could give you more."
