1983-P Jefferson Nickel With Grease-Filled Dies?

This MAY NOT be a Greaser situation. I have a coin that was identified as a 'Hard Planchet' strike by Mike Diamond several years ago and it too is a 1983-P Jefferson. He said he had seen several like this with the same date.

His explanation was that a batch of hard planchets (possibly not annealed) was sent to the mint. The metal of the planchet was far too hard to accept the full image from the dies because of this with the missing detail at the center of the strike, which is the opposite of how most Grease Filled Die strikes appear.

This is the coin. It was the second coin image I posted on the CCF way back in 2011 and attributed by Mike Diamond .



Sorry about the quality of the images. I was still using a flat-bed copier way back then for some of my pictures.

Very nice photos! I agree with Yokozuna that this is not a Grease Fill issue. Here is a post from 2011 where Mike describes the error http://goccf.com/t/100964&SearchTer...ard,planchet

Thanks for that information, Yokozuna and CoinHI! I thought it looked odd for a grease-filled die centrally filling both sides, but I couldn't think what else it could be. And I never heard of a "hard planchet" strike before. I mentioned in the first post that I had two coins that are very similar. I just shot some photos of the second one as well. The top set is the coin in the original post, and the bottom set is the other one. Very interesting!

Here's an article written by Mike Diamond several years ago discussing these hard planchet strikes.

Interesting. So it has the appearance of a planchet with insufficient metal to fill the high devices, but with a normal mass and a different cause.

Those too-hard planchets must have caused quite a bit of die stress.

Well done!

Excellent & Interesting info on this one!
