NGC-certified Sovereigns with Mint Errors Offered in Heritage Sale

Posted on 8/6/2022

The British gold coins are each expected to sell for tens of thousands of dollars in the August auction.

Two Great Britain Sovereigns with spectacular mint errors that are certified by Numismatic Guaranty Company™ (NGC®) are being offered by Heritage Auctions. Online bidding is underway for the World & Ancient Coins Platinum Session and Signature Auction, which will be held August 25-28, 2022.

One is a stunning 1863 Great Britain Gold Sovereign graded NGC Mint Error MS 66 – Struck 50% Off Center. Off-center strikes occur when the planchet is not properly aligned with the dies when it is struck. In this case, only half of the Sovereign planchet was correctly in place between the upper and lower dies, so much of the design is missing. This rare coin has an estimate of $35,000 to $40,000.

The auction has a second 1863 Great Britain Gold Sovereign with an impressive error, this one graded NGC Mint Error MS 66 – Double Struck 85% Off Center. Double Strike errors occur when a coin fails to eject properly after it is struck by the dies. In this case, when the dies struck again, the second strike was imparted near edge of the coin. This coin has an estimate of $25,000 to $30,000.
