This may just be my dream coin. I won't own it but I can stare at the photos. Feel free to guess the grade and use the poll. And yes that is the entire coin and it's not a details coin. Bonus point if you can figure out what it is.
First thought that comes to my mind is that the coin was struck on the wrong die, like maybe it was fed into the machine striking quarter dollars, but I'm probably way off base. Any way, I'd grade it a '65 but I bet they gave it a '66.
Wrong die, or wrong planchet? Take a look at the reds around the devices. This is copper. I'll guess Ms-66 is the grade, but this is clearly a Franklin struck on cent planchet (well, unless its a foreign copper planchet, of course - what's the weight?)
Good call. Wasn’t looking at the surface, just trying to figure out the size. All that toning didn’t help, either.
Irregular shapes like this are standard for off-planchet strikes. It starts as a round planchet, but since the planchet is not large enough for the striking chamber, the metal will flow into whatever devices are closest and take the metal away from the edges. On a normal strike, the planchet is just slightly smaller than the final radius - the rim and edge that is developed is only possible because the pressure of the strike causes the metal of the planchet to fully flow into all of the crevices of the dies (all three of them).
I actually wrote BN and then went back to look and noticed the holder said RB. I wouldn't call it RB, but with this coin it likely doesn't make much of a difference.
The superior strike, surfaces and color can all be attributed to the error because this design is not made to be struck on so little surface area, and because the copper toned so beautifully. If the grade is extremely high, and was assigned to reflect those superior attributes, the error gives this Franklin an unfair advantage over its brethren. I'm guessing the TPG forgot to account for that, and graded the coin 67.
Physics fan beat me to it but I immediately thought beautiful toned franklin on a cent planchet. I debated hard between rb and bn I finally thought 65 bn. But a premium bn. Either way I like it a lot and I’m not usually a fan of most errors or modern coinage. Bit I’d be happy to own this one
The auction description mentions a Franklin struck on a Cent in a top 100 reference, but I don’t think it’s the same example.
