GREAT BRITAIN. Mint Error -- Struck on Copper-Nickel 6 Pence Planchet -- Pence, 1974. Llantrisant Mint. ANACS AU-55.
cf. S-B1 (for regular issue); cf. KM-915 (same). Weight: 2.78 gms. An interesting error featuring a 6 Pence planchet that would have no longer been in use. Owing to their similar size, one which would not initially be quickly noticed, as is evident by the time spent in circulation.
Estimate: $75 - $150
