I tend to agree with you, it is not a Greaser. Quote:
This 2008-P Andrew Jackson dollar coin did not receive a full strike. Insufficient ram pressure (applied tonnage) or insufficient die approximation are the culprit in this case. This error is often erroneously called "a die adjustment strike". http://www.error-ref.com/?s=die+adjustment  Edited by Chase007

When you say 'die adjustment' are you meaning that the dies were adjusted to far apart at their strike point? Therefore leaving such a weak strike?

Some experts will see the rims and think Struck Through Grease. While some think adjustment strike is plausible as the rims start to develop as soon as the planchets expansion reaches the collar and begins back filling. I think verify the weight first, then if weight is normal pick a corner above. I'll choose the later in this case. Thanks, Doug. Quote:

I'm thinking length of strike, as in duration. There is a balance. If pressure is adjusted or applied and released to quick on a proper spaced pair of dies. Details should be weaker, compared to holding pressure ten thousands of a second longer. Metal expands or flows under pressure. The longer pressure is applied the more expansion and better chance for all recesses to fill in. Edited by Halo1st

If it's a Greaser it'd be the smoovest one I ever done see..! And, of everyone on this site I 'know' I'd trust you the most to make a Greaser call, Raymo.. So yeah, I'm in agreement with you n Chase.. Swamp |

It does have pretty nice rims and most of the certified die adjustment strikes I've been looking at don't.   Oregon coin geek.....*** GO BEAVS ! ! ! ***

But since it is really a pressure issue ( pounds / tons per sq. in. ) and without looking it up, I believe it's more about how close they finish up to one another on their planchet side then it is about how far apart from one another they begin each strike.. Either that or continuous held pressure at a fixed distance.. "Die adjustment" is somewhat erroneous terminology.. Swamp |

I'm just going by terminology used by PCGS/NGC. I'm not sure what the correct term is.

The coin in the image that is a grease, I bought and my instructor thought it was a trial strike. But we learned later we were both wrong. I believe Mike Diamond straighten us out then. Wow about 20 years ago. But do not regret buying the coin. I've posted it hundreds of time. (the Struck Through Grease cent) |
