This is the "premium" version of the United Kingdom Proof Set of the year, including the regular circulating coins plus some of the commemorative coins issued throughout the year.
The 2020 set includes the King George III £5 (crown) commemorative marking the 200th anniversary of his death, plus three commemorative £2 coins: VE-Day, Agatha Christie, and Mayflower; these coins were only issued in the year's sets and not released into general circulation. Also included is the Team GB 50 pence coin issued for the Olympic Games in Tokyo which did not actually happen in 2020.
The rest of the coins in the set are all the regular circulating coins, from the definitive Britannia-type £2 down to 1p.
The coins are struck in Proof FDC grade with frosted finish. The set also contains a £2-sized bimetallic Royal Mint medal and a numbered Certificate of Authenticity. |
