(ABC News) Maria Rivera might want to consider a second career as an appraiser.

When the longtime product manager at the Goodwill Donation Center in Manassas, Va., spotted a painting that stood out amid the other donated goods last month, she pulled it aside and sent it to the nonprofit’s e-commerce team in Washington, D.C., which researched the painting and found it was a work of Giovanni Battista Torriglia, a late-19th century Italian painter.

Not knowing more about the specific painting, Goodwill put it up for sale on ShopGoodwill.com, it’s own version of eBay, and watched in amazement at what happened next.
