For those with an interest in error coins the forthcoming sale will feature a rare 20p Error Coin with Royal Mint certification.

This 1990 20p has been struck on a copper-plated steel blank intended for one of the other countries the Royal Mint produces coins for; a spectacular error and the only one of its kind known, on discovery the coin was featured in the national press.

Following a strong showing for British and Foreign gold coins in the last sale, the forthcoming sale features an extensive gold section.

With a nice selection of early milled British gold and later sovereigns, together with interesting foreign examples from many different countries, this sale is likely to appeal to collectors of gold.

The first example to be sold at Tennants of gold featuring the bust of our new king, Charles III will also be included in the form of a 2022 4-Coin Gold Proof Set, struck in memory of Queen Elizabeth II and one of only 750 made (estimate: £1,200 –1,600 plus buyer’s premium).
