Great Britain 1975 5 pence
The first specimen was lot 34184 in Heritage sale 3082 (New York, January 2020), where it sold for $180. The catalog description[1] noted, "Great Britain: Elizabeth II Mint Error - Wrong Planchet 5 New Pence 1975 MS65 Red and Brown PCGS. Struck on a Penny (S-B1) planchet." This five new pence, or 1/20 of a pound, was introduced in 1968 as part of the decimal reform. It was struck to the same module as the superseded shilling, which had the same value. It was struck in this style until 1982, when the word "new" was dropped from the reverse. The module was reduced to 3.25 g in 1990. Some dates, such as 1972-74 and 1981, were struck only for collector sets.
Recorded mintage: 141,539,000 plus 100,000 proofs.
Specification: 5.65 g, copper-nickel, 23.5 mm diameter.
