The 1979 pennies weigh 3.24 Grams. and have a diameter of 19.05 mm.
The lighter weight of yours would account for the lack of beads.

The tolerances for weight is quite large... it could be struck on a Barbados bronze 1 cent planchet.
Or, it just could be a planchet struck on a strip that was rolled too thin, or near the end of a bronze strip whereby the thickness tapered out. For some reason, thin planchets are relatively abundant from 1979-1981...

So what would be the best way to find out about if it is a wrong planchet apposed to a thin or tapered planchet Should I send it in to get graded (PCGS) as it is a nice high mint state coin regardless what kind of error coin it is. |

As SPP has said in the past...PCGS charges a lot more for "Error" coins..and shipping and ins..+ +..etc.. So my vote would be a "no" and maybe wiser to get it properly graded locally.. |

If it was my coin, yes I would send it to PCGS. But then again, I have a bias for really nice high grade 1c errors.
The trick is - try to determine what it is before you send it - or it will just come back as "struck on a foreign 2.7 gram planchet"... or "struck on 2.7 thin planchet"
What is the diameter of the coin? What does the edge look like - rounded (weak to no collar) or square (full collar), etc...

Admitting that I don't know a whole lot about this type of error coin other than I know its not normal to the eye. But under the supervision of others especially SPP I am learning I think. The coin is the same size as a regular 1979 cent if any thing it might be a little smaller hard to tell, it seems to be about 1/2 cm regular coin 1 1/2 cm so a lot thinner, it has a bit of a slightly raised rim higher in some area's than other areas where it seems to fade away looking at it on edge looks flat but very thin.
So I'm leaning toward a thin planchet error coin high grade MS-65-66 at least.

CT has digital micrometer callipers often on special at $9.95...just watch for the specials...
Any post office should be able and willing to tell you the weight..(metal plate..so place a slip of paper under it)

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.
