Overview

Historical significance

1982 was the first year of issue for the twenty pence coin in the UK. The coin was introduced to fill the gap between the 10p and 50p coins. Because the 20p is normally silver-colored cupro-nickel, a copper-colored version is either a rare mint error (wrong planchet), a trial piece, or altered/plated post-mint.

Estimated value

$10.00 - $300.00 (Highly dependent on authentication as a genuine mint error versus post-mint chemical plating)

Care & preservation

Handle by the edges only. Store in a PVC-free coin flip or capsule to prevent further oxidation or environmental damage. Do not clean or polish, as this significantly reduces numismatic value.
