Sotheby’s will offer the sole 1933 Saint-Gaudens double duty certified as lawful to have by the U.S. government in an auction set for June.

The coin is owned by Stuart Weitzman, a noted fashion designer. The identity of this coin’s owner had been a closely guarded secret until now.

The June 8 auction consists of just 3 lots, and contains two great rarities from the philatelic world, according to Sotheby’s:”the British Guiana One-Cent Magenta, the most well-known and valuable stamp on earth; along with The Inverted Jenny Plate Block, the many well-known and sought American American stamp rarity.”

This is breaking news. Coin World will have more in-depth coverage later.
