Thanks for the link SPP I ordered one never thought of getting one of these makes sense I have every thing else listed but really need more knowledge.
I don't think it would be Barbados planchet SPP they weigh over 3.+g.
But the New Zealand planchet might fit this coin they weigh 2.+g I searched for more info and found 3 other 1979 Canadian pennies graded by NGC on New Zealand planchet with weights of 2.+g and they look very similar but showing more beads than this one.
So now I'm back to being undecided thin planchet or wrong planchet so I'll wait until the new digital micrometer arrives I'll take better measurements for thickness and diameter.
