A 1747-Mo-MF gold 8-escudo coin of Ferdinand VI bearing the rare
“Imaginary Bust” design highlighted Heritage Auctions’ Aug. 13 sale of
coins from the Isaac Rudman Collection of Mexican Coins.
The coin, graded About Uncirculated 58 by Numismatic Guaranty Corp.,
realized $47,000 U.S., including the 17.5 percent buyer’s fee.
The Imaginary Bust issue was struck after a Royal Ordinance of July
31, 1746, sent from Madrid to the Mexico City Mint, arrived in Mexico
in May of 1747. The royal order called for a change in coinage legends
and design to reflect Spain’s new king, Ferdinand VI.
Shortly after receiving the order, interim director of the Mexico
Mint Andres Morales de los Rios proposed to Viceroy Juan Francisco de
Guemes production of new dies with a bust imagining the new king’s
appearance, while awaiting instructions (and punches of the new king’s
bust) from Spain.
Punches with the official Madrid-engraved bust of Ferdinand VI were
received in Mexico City at the end of 1747, so “Imaginary Bust” issues
of various denominations were struck only as a one-year type. The
large 8-escudo coin is the most famous “Imaginary Bust” coin, though
the other denominations are as rare or even of greater rarity,
according to Heritage. The Rudman Collection is the first to offer a
complete set of Imaginary Bust coinage.
