A one-of-a-kind California Gold Rush coin will return to Baltimore for the first time since it was sold by The John Hopkins University more than a quarter century ago.

A multi-million dollar educational display of California Gold Rush era treasures will be exhibited during the Long Beach, Coin, Stamp & Collectibles Expo, June 1 - 3, 2006.

The first U.S. gold coin, hand-struck in 1787 by a goldsmith who was George Washington's neighbor and called the single most important coin in American numismatics, was purchased for $2.9 million last month by Steven L. Contursi, a rare coin broker from Laguna Beach.
