PORTLAND, Ore. (AP) - A painting dropped off at Goodwill by an anonymous donor sold for $165,002 Thursday during an auction on the organization's Web site.
     
Bidding on the painting, a 1923 watercolor by the American impressionist Frank Weston Benson, started at $10 on Oct. 12. The bidding soared after the painting was authenticated by the owner of a Portland gallery.
     
The name of the winning bidder has not been revealed.
     
Dale Emanuel, spokeswoman for Goodwill Industries of the Columbia-Willamette, said that the nonprofit gets a lot of valuable donations, but that it's unknown whether the person who dropped off the painting knew its worth.
     
"We get donations that have come through the generations of a family, and as it goes from one person to the next the true value may not be understood," she said. "I've seen that many, many times."
