NGC is proud to have been selected to certify more than 200 of the finest coins in NGSA's fifth auction, which was held in Geneva, Switzerland, on December 2 and 3, 2008. The sale was a celebration of both the 20th anniversary of NGSA and the unveiling of NGC's ancient coin certification program. NGC was the sole certification company represented in the offerings of NGSA, which became the highest value coin auction ever conducted outside the United States.
