sel_69l Bedrock of the Community Australia 21788 Posts	Posted 08/26/2022 07:08 am Most probably a foreign planchet. For instance, It could be struck from a planchet intended for another British Commonwealth country, that has the same specifications as the British 5 Pence coin. The RCM has produced circulating coinage for over 70 countries around the World. Perhaps impossible to say exactly which Country, because the weight specification would match perhaps 5 or more of those Countries. Edited by sel_69l 08/26/2022 07:19 am Report this Post to the Staff

Tgzander New Member Canada 4 Posts	Posted 08/26/2022 2:13 pm Thanks for the reply guys looking through what the mint made in 78 I can only really seam to match it to a barbados 25c planchet (5.6 gram - 23.6mm) or a cayman islands 25c proof planchet (5.7 grams - 24mm) Standard canadian 25c is 5.07 grams - 23.88mm Comparing all aspects of the coin and mine being slightly larger at around 23.9mm +- 0.1mm I'm leaning towards a cayman islands planchet Report this Post to the Staff
DBM Pillar of the Community Canada 9864 Posts	Posted 08/26/2022 4:37 pm More likely the Barbados planchet. A 24mm planchet would not fit in the press but a 23.6mm planchet would easily expand on striking. "Dipping" is not considered cleaning... -from PCGS website Report this Post to the Staff
Tgzander New Member Canada 4 Posts	Posted 08/26/2022 5:41 pm On 2nd look there's also the new 1978 new zealand 10c planchet (5.66 gram 23.62mm) I'll have to source one to test trace elements for comparison Edited by Tgzander 08/26/2022 5:42 pm Report this Post to the Staff
