2021 One Ounce Britannia Gold Coin Uniface Obverse Mint Error NGC MS69

A 2021 Britannia one ounce gold coin from The Royal Mint. Struck with uniface mint error.

This type of error occurs when two coin blanks enter the press instead of one. Each blank only receives half of the design - in this case the reverse is fully struck showing Britannia standing with trident.
