Help On This Jefferson Requested {weak Obv. / Strong Rev.}

I think it is pretty safe to say that this isn't a capped die strike. It doesn't have the distorted image on the obverse that this type of error will cause. This could possibly be a die testing piece, or simply an overpolished die. I am leaning toward the overpolished die, as I believe that a die test piece would exhibit a soft strike on both sides. But I will divert to the experts, who are probably all sleeping right now! Looking forward to hearing what they have to say.

I'll have to agree with John1 on this, it's impossible to get a weak strike on one side of a coin without some kind of interference like oil or grease filling the die. ~ Jim

It's a grease strike through. Not a capped die because it lacks the distortion that would be seen even with a very late stage cap. It isn't a weak stike of "set up" piece because if it was both sides would be weak. And it isn't an overpolished die because it is the high points or the DEEP areas of the die details that are missing. On an overpolished die the high point details will still be there and the shallow design detail will be missing.
