King George V (1911-1936) Mint Error
NGC PF 64
UNIQUE DISCOVERY COIN
By Mike Byers for Mint Error News ……
This unique 1970-S Proof Quarter mint error from the United States was overstruck on a Canadian Quarter that circulated during the reign of King George V from 1911-1936. It was authenticated and certified by NGC as PR64. This was most likely from the group of San Francisco Proof Mint Errors that was auctioned by the State of California.
There is a significant amount of detail on both sides showing the design of the Canadian Quarter. This is a flip-over where the obverse design of the Canadian Quarter which shows the portrait of King George V is visible underneath the U.S. Quarter reverse design.
The reverse design of the Canadian Quarter showing the wreath is visible underneath the U.S. Quarter obverse design. This is one of the most fascinating and intriguing Proof mint errors ever discovered.
Proof coins are struck by technicians who hand feed the blanks into special presses. They are produced, examined, and packaged using extreme quality control. It is very unusual to find major proof errors. A few broadstrikes, off-centers, double strikes (in collar), and off-metals have been known to be found in sealed proof sets. Proof errors are aggressively sought after by many error collectors.
A very small group of Proof errors recently came from a collection that was auctioned by the State of California. The United States Secret Service inspected and released this collection to the State of California determining that it was legal to own. The State of California then auctioned the collection and it has been dispersed since the sale.
A different 1970-S Proof Quarter from the United States was overstruck on a 1941 Quarter from Canada. It was authenticated and certified by NGC as PR65. The unique 1970-S Proof Washington Quarter overstruck on a 1941 Canadian Quarter is the only one known with King George VI. It went viral and was featured on Fox News, USA Today, and countless other publications.
