Rare Sacagawea Dollar Mule Is Among NGC and PMG Collectibles in Long Beach Auctions

combines the Sacagawea Dollar reverse
and the Washington Quarter obverse.
US, world and ancient coins certified by Numismatic Guaranty Corporation® (NGC®) and banknotes certified by Paper Money Guaranty® (PMG®) are expected to attract significant interest from bidders at the Long Beach Expo of coins, currency and other collectibles.

It was struck on the manganese-based alloy planchet used for the Sacagawea Dollar.
