Okay, after going through quite a lot of cents the past couple of weeks, I have run across dozens of 1979-D cents with filled/damaged mint marks. Not really a surprise since I live in Denver. LOL I ran across this LMC last night and noticed it looked a bit different than all of the rest. First, I should say that I have been using the book "Strike It Rich With Pocket Change" 4th Edition by Ken Potter and Brian Allen. It shows a 1979-D LMC with a doubled mint mark. The photo in the book looks exactly like all of the damaged 1979-D LMC mint marks that I have seen. It does give a reference to Wexler as 1979-D WRPM /RPM 001, but I cannot find it on his website.

This is my confusion-- is there a way to tell a 1979-D LMC mint mark that is doubled from a a 1979-D LMC mint mark that is damaged? Is this book accurate or inaccurate? I cannot find any other references to a 1979-D LMC doubled mint mark. Does a doubled mint mark even exist for this coin, or are they mostly all just damaged? Is the book using the term doubled when it should be using the term re-punched?

On to the coin I am showing-- I cannot tell if this is an RPM or PMD. I have found photos of re-punched 1979-D LMC mint marks, but none look like this. I am noticing what looks like PMD coming down through the horizontal edge of the 7. I am wondering if this is PMD and just continued down to damage the mint mark? So, is the book I am referencing misleading in some manner? Are there indeed three different versions of the mint mark for this coin-- doubled, damaged, and re-punched? Please help me to understand the 1979-D LMC mint mark varieties better! Thanks!

The only known 79-D LC damaged mintmark that I am aware of [and which is known] has a small chunk taken out of the SW corner. Sorry, cannot find my pic right now.

What you show in your pics looks more like it is from Die Deterioration &/or circulation wear than from any doubling.

Not sure about answers to your questions about the book, but the authors are quite knowledgeable.


For info on Lincoln cents, I would highly recommend using http://www.lincolncentforum.com as they specialize in that coin.

update: I have that very same book and see what you are referring to on page 75. What I am seeing from the photo looks to be a split-serif RPM. The broken die mm looks very similar on the bottom serif but does not have the upper split serif.

Unfortunately, varietyvista pics are sub-par: http://www.varietyvista.com/02b%20L...9DRPM001.htm

There are three on CCs' site https://coppercoins.com/
Your coin looks like a damaged mint mark punch and maybe MD?

The mintmark punch damage is seen on other denominations as well. Your coin looks like an example of that. But the mintmark looks also damaged. Try taking another image of the date area at a different angle. That may show if it is damaged or showing Machine Doubling?
