The Seminole County Sheriff's Office bomb squad couldn't figure out what was inside even after the box was X-rayed.
So, deputies blew it up.
"It didn't look normal," sheriff's spokeswoman Kim Cannaday said. "That's all we knew."
The result: More than $2,500 in paper money was turned into confetti. Four hundred ninety-eight rolled silver dollars remained intact, Cannaday said. The church won't be out any money, though, because the U.S. Treasury will replaced damaged paper money, she said.
The bills were estimated to be worth $2,500 to $2,700. The silver dollars may be worth more than $1 apiece, depending on their year minted and condition.
