KANSAS CITY, Mo. (AP) -- We've seen rings dropped into donation containers locally, but a Salvation Army spokesman says someone has dropped a gold tooth into a holiday collection kettle. Spokesman Rick Carroll said Thursday that he's found diamond rings, silver bars and four-leaf clovers but has never heard of a tooth donation. He says the item could be worth $100 depending on the amount of gold it contains. Kansas City's Red Kettle Campaign began Nov. 7 and is currently running about $50,000 behind where it was a year ago. Carroll says he at first considered the donation to be gross, but now thinks it's a nice gesture. He worries that the donation might have been unintentional and he is temporarily hanging onto the tooth in case someone claims it.
