Shelley Henderson of the Salvation Army said the rings were found wrapped in a $10 bill last weekend in Raleigh. Other valuables have been donated in other locations across the country, including a $2,000 diamond and sapphire ring in Miami, The Charlotte (N.C.) Observer reported Wednesday.
Henderson said this isn't the first year that wedding rings have appeared in the donation kettles.
"They don't get there by accident," Henderson said. "I was floored when I first heard about it."
