Jim0815 Pillar of the Community United States 5240 Posts	Posted 07/10/2018 9:21 pm I found this 1988 D LMC with the thickest mintmark I have ever seen. It is almost three times thicker than the numbers. Why would this devise be so much thicker than the devises above it? Edited by Jim0815 07/11/2018 07:55 am Report this Post to the Staff

Jim0815 Pillar of the Community United States 5240 Posts	Posted 07/10/2018 9:34 pm It is for sure! I see no signs of grease or abrasion on any of the other devises to make them thinner. Everything is of normal size and depth. Report this Post to the Staff
Errers and Varietys Bedrock of the Community United States 75233 Posts	Posted 07/10/2018 9:51 pm Jim, maybe they made the mint mark punch a little too thick? Errers and Varietys. Report this Post to the Staff

Waynoah83 Pillar of the Community 586 Posts	Posted 07/10/2018 10:56 pm Maybe they had to do some polishing there and thought the mm was getting a little skinny so they repunched it and it went a little deeper than normal. That would possibly explain why there's such a discrepancy in size and height too. This coin might be a late die state and having the mm repunched on the die, on top of the old one, you end up with something like this. We all know those 88's are notorious for polishing and the D's are usually pretty skinny. That's just my theory. Don't know if any of the above mentioned is even feasible. Just throwing this out there, do any mints produce for other mints? Did Philly make some for Denver and have a Diff mint mark? It doesn't look like it's in the usual spot.

coop Bedrock of the Community United States 62064 Posts	Posted 07/10/2018 10:59 pm Keep in mind the mint mark is added to the die by hand till 1990. So if the punch set it that deep, it would be normal for that year. Not a RPM. Just a deeper set mint mark into the die. Now taller on the coin than the date devices. Report this Post to the Staff
Jim0815 Pillar of the Community United States 5240 Posts	Posted 07/11/2018 05:22 am Thanks Waynoah and Mr. Coop. After doing a little research error-ref calls this a deeply punched mintmark. They are not for sure what exactly causes it but it's unusual in the fact that the interior of the D is just slightly below the devise yet higher than the surrounding fields. Error-ref actually have this as a variety. Edited by Jim0815 07/11/2018 05:50 am Report this Post to the Staff
Jim0815 Pillar of the Community United States 5240 Posts	Posted 07/11/2018 07:07 am @coop, the info I found on V.V. shows that the mintmark used for 1988 D was the MMS-012, 1987 D's used the MMS-011 with a few using the MMS-012. On the error-reference site they explained the deep punched mint mark referencing the 1987 D as the year with the deep punched mint mark and had a couple of pics of of them. The more I look at this cent the more I am convinced the mintmark on my 1988 D is a MMS-011. Edited by Jim0815 07/11/2018 07:39 am Report this Post to the Staff
