NEW YORK - A COLLECTION of more than 3,000 inverted stamps has sold at auction in New York for more than US$5 million (S$7.3 million).
The two-day auction by Spink Shreves Galleries ended Friday. The collection was amassed by Pittsburgh stockbroker Robert H. Cunliffe, who died last year.
Charles Shreve, president of the Dallas-based gallery, says it was the most comprehensive collection of inverts ever formed.
