This is a sub-set of the standard United Kingdom Proof Set of the year, including some of the commemorative coins issued throughout the year, but not the regular circulating denominations.
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.
All coins in this set are struck in Sterling Silver to Proof FDC grade with a frosted finish, and are piedforts (double the thickness and weight of regular silver proofs). |
