Yikes, quite a diversion! Well, I am a late milled fan but always like to hear of other coins.
However, I am interested in some of the coins coming from the 1960-70 period - knowledge, but if possible collecting them - this would exclude the halfpennies and pennies struck in gold!!!
I have the 1964, 65, 66 and 1967 pennies struck in CuNi. Interesting that there should be such a run, but wonder what else was going on at the mint. Was it all "shenanigans" performed on after-hour shifts, or just what?
But back to the original topic: I will likely get this coin certified as there is trouble in many quarters accepting it otherwise. Not that TPGs are infallible, but because that will give the coin somewhat greater plausibility.
