Heritage offers rare gold error

It’s what’s inside that counts.


Heritage Auctions will put a one-ounce gold American Eagle on the block that is struck on the wrong planchet.

Instead of the standard .9167 fine gold, the coin is actually .9999 fine, meaning it was struck on a blank intended to be a gold Buffalo bullion coin.

Heritage says it is the “only known U.S. gold wrong planchet error.” Bidders will vie for it at the 2017 Florida United Numismatists Auction, Jan. 4-9 in Fort Lauderdale. “Wrong planchet errors are virtually unknown in the U.S. gold series,” Heritage Auctions President Greg Rohan said. “There have been exceedingly rare instances of non-gold coins struck on gold planchets, but this is the only certified U.S. gold issue struck on an incorrect gold blank.” Though the gold Eagle and American Buffalo $50 coins have the same 32.7mm diameter, they differ in thickness and weight. Due to the American Buffalo’s finer composition, it is thicker and lighter. The coin is graded MS-69 by the Professional Coin Grading Service. One other is thought to exist, but it is not yet certified. APMEX officials discovered the error and conducted non-destructive fineness tests.

Heritage will also be auctioning world coins and paper money. Details on
