An uncertain number of the 10 Proof 2017 In the Eyes of the Timber Wolf gold kilo $2,500 coins sold by the Royal Canadian Mint were mistakenly produced with the obverse die of the Proof silver $250 version, creating a mule error.
Both obverses feature the effigy of Queen Elizabeth II but feature different denominations. The coins were struck at the RCM facility in Ottawa.
The mule errors were confirmed Aug. 2 at the American Numismatic Association World’s Fair of Money in Denver by Alex Reeves, RCM senior manager of communications.
The fallout from the Enhanced Uncirculated Coin set release: Another column in the August 21 weekly issue of Coin World re-veals that while forms of numismatic literature like fixed-price lists were meant to be fleeting, they can actually be quite useful.
RCM officials are attributing the mule to “human error,” Reeves said.
A mule is a coin, medal or token struck with obverse and reverse dies not intended to be paired together.
Reeves said the RCM estimates that four of the mule versions of the .9999 fine gold kilo coins are being privately held and a fifth is in the RCM’s inventory.
According to Reeves, the RCM had already shipped nine of the purchased coins and was preparing to ship the 10th coin sold to a customer when staff noticed that the piece had the wrong obverse, with the $250 denomination.
A new piece was struck with the correct $2,500 denomination and delivered to the customer. The mule was retained by the RCM.
