A Secret Santa discreetly dropped off a rare gold coin valued at $1,700 in a University Place Salvation Army kettle this past week.

But that act of kindness may not be as rare as it seems.

The South African Krugerrand was found by a volunteer bookkeeping on Wednesday.

However, The Tacoma News Tribune reports (http://bit.ly/tuQ17l) that other Krugerrands have been donated to the Salvation Army across the country, from Georgia to Nebraska. And someone, possibly the same person, also donated a Krugerrand at the same location in the past two years.

Local Salvation Army officer Major Warren Dabis says the coin was wrapped in a dollar bill.

Salvation Army officials are working with a local coin dealer to sell it for the highest bid.
