I have attached a photo of the mintmark for my coin.

I sent this coin to NGC. They sent it back in their slab with a pretty good rating. However, they did not mention the mintmark. They included a small label with the following text.

"This NGC coin, Certification # 8395176-001 has not be attributed by NGC for the following reason: Not a DDO, DDR, RPM, RPD, or MPD"

I have four of these coins. My question: What is it? Clearly, something is under the mintmark.

To CCF! Maybe a damaged mint mark punch?

You can see that bump on a number of proof nickels listed by PCGS. If I had to hazard a guess, it's probably just the backing of the S mint mark punch. They are often not polished flat. Most of the time, the engraver doesn't hammer deep enough for the back of the S punch to make contact with the die face.

It's not under the mm just inside of it. I always liked the term "die poop". I think Alan on VAMWorld may have coined it. Just something on the die, damage wear, who knows, it can come and go through a dies life. Less common of course on proofs but they still try to get all they can out of those dies too. Marked up pics to show how this is a later stage of this proof.

Thank you for all the warm welcomes and for your ideas about what may be causing this condition. This appears enough times that I am surprised that it hasn't been recognized and given some provenance and recognition as an error or flaw.

If I am ignorant of some of the rules regarding this, please forgive me. I am somewhat old to begin coin collecting, but I enjoy it even if I'm late to the game.

I'll be 84 next month and learned something new just a few days ago. I hope you enjoy your adventure as much as I have.

I thought this was associated with a broken mint mark punch used in 68 and 69.... across all demonanations.

Greasy, that particular mm ran through 73 (MMS-005) and you may be right about the broken punch but are you thinking of the MMS-006/MMS-002 that was reinstated from the 40's, the worn out punch?

Again, thanks to everyone who posted. I have ideas now to pursue.
So far, this has been a very friendly group, especially compared to most of what I see on the internet.

To JFEED, okay, you got me by about two years. My grandsons live overseas, so I try to do things when I see them and send them gifts for their birthdays and Christmas that give them a little bit of the US. I began sending them a US coin every Christmas, beginning with pennies from my birth year. Eventually, I ran out of coins from that year, began looking around for more, and became hooked. I look back at some of the stuff I bought when I began and wonder what I saw in them. I've been burned a few times on ebay, but I'm learning.
