British error penny on a foreign planchet

[will1976]

I'm trying to identify the planchet which this penny has been minted on so I can add one to my collection for reference. Weight is 2.6 grams 20mm diameter brass and non magnetic

Going from Proof Sets I have handled and the shape it would be worth looking at Sudan, Swaziland or Ceylon, Royal Mint produced coinage for all around that time

A date would help. The picture is too small. 83, 86 or 88?

All you have to do is plough through Krause until you find a suitable match. It's a bit tedious, that's all.

Do it systematically, i.e. start at the beginning, otherwise you will be revisiting old territory. Sod here can guarantee it will be Zambia or Zimbabwe
