Greg Manning Auctions' Spectrum Division Named a Primary Distributor of S.S. Republic Coin Discovery.

WEST CALDWELL, N.J. & IRVINE,Calif. -- Odyssey Marine Exploration Finds 1865 Shipwreck Treasure Valued at $75 Million

Greg Manning Auctions, Inc. (NASDAQ:GMAI) announced today that Spectrum Numismatics International, a wholly owned subsidiary of GMAI, has been named one of the primary distributors to market an important discovery of gold and silver coins estimated to be worth at least $75 million. Primarily minted between 1838 and 1865, the wreck of the S.S. Republic was recovered by Odyssey Marine Exploration Company (AMEX: OMR). The S.S. Republic was bound for New Orleans from New York City in 1865 when on October 25, a northeast gale, described by the ship's captain, Edward Young as the "perfect hurricane," caused the order to abandon ship in forty foot seas off the Georgia coast. Of the 92 passengers and crew on board, all but two made it safely aboard lifeboats and a raft. However the ship's cargo, that included a reported $400,000 dollars in gold and silver coins (1865 value), as well as a large shipment of freight, quickly sank to a depth of 1,700 feet. Odyssey, after a twelve year quest using state of the art equipment, finally succeeded in its goal to locate the S.S. Republic and its thousands of coins, many in uncirculated condition and valued at up to $450,000 each.

Spectrum Numismatics International has previously marketed a number of fabled coin discoveries including the Binion silver coins and the Wells Fargo $20 gold pieces. Greg Roberts, C.E.O. of Spectrum stated, "Coins with the provenance of the S.S. Republic will forever be identified with this famous shipwreck and this important era in the history of our country and our nation's coinage of beautifully designed and executed gold and silver pieces." He went on to add, "We are working toward an agreement with the Odyssey group to auction a select few coins in our Bowers and Merena and Teletrade divisions. Spectrum will be selling the majority of the S.S. Republic coins to individual investors and collectors through Goldline International, Inc. (www.goldline.com), a precious metals and rare coin investment firm founded in 1960. Spectrum previously worked with Goldline in the successful distribution of the Binion Silver Dollar Collection and Wells Fargo 1908 No Motto $20 gold piece hoard.

Greg Manning, First Vice Chairman, CEO and President stated, "Spectrum and GMAI look forward to working with Odyssey in the future as they continue to search for important shipwrecks around the world. We expect that the sale of the S.S. Republic coins will have a positive impact on the first and second quarters of our fiscal year 2005 which began on July 1st."

The story of the sinking of the S.S. Republic is a feature article in the September issue of the National Geographic magazine. To learn more about this amazing discovery go to www.nationalgeographic.com, www.shipwreck.net, and www.goldline.com.
