In 1855, Ferdinand Grüner cut the dies for a round-format fifty-dollar gold coin for Kellogg & Co., but coinage seems to have been limited to presentation pieces. Only 13 to 15 pieces are known to exist. A "commemorative restrike" was made in 2001 using transfer dies made from the original and gold recovered from the SS Central America. These pieces have the inscription S.S. CENTRAL A M E R I C A GOLD, C.H.S. on the reverse ribbon. Proof cameo frosted surfaces.
