She bought a vase at Goodwill for $3.99. It was a rare piece that just sold at auction for more than $100,000.

A rare vase by an Italian architect recently sold at auction for $107,100 — even though at its previous sale, it went for just $3.99. The vase by Carlo Scarpa was sold by Jessica Vincent, a thrifter who bought it at a Goodwill in Virginia. 

To the untrained eye, the vase may seem like a normal glass piece with green and red streaks, but the Wright auction house, which handled the sale, says it is one of the rarest pieces they've offered in more than a decade — part of Scarpa's Pennellate series for Venini, produced in 1942.

The technique ("pennellate" means brushstroke) is achieved when the piece is being blown by adding in colored opaque glass. The pieces in this particular series were difficult to make, so the numbers are low.
