possible new variety? 1960-D like RPM-3 but no marker match

[coppersleuth]

I have an interesting pair of 1960-D cents.

In closely reviewing the coppercoins website photos, I was initially certain that both coins were RPM-3. However, there were certain aspects that began to puzzle me.

First, neither of my coins match any of the EDS, MDS, or LDS markers (at least as far as my scrutiny was concerned).

Second, both of my coins have an identical and fairly significant die crack. It starts to the left of the middle ear area and runs slightly north-east across the top of the ear and a bit beyond. IN reviewing the RPM3, as well as the RPM2 and RPM5 markers, none of the markers mentioned this die crack which I imagine would be used due to its prominence.

Third, notice that the second D, specifically the area along the west or left side of the primary D, has a different prominence between the two coins. Coin 1 has a more obvious separation, while coin 2 is very weak in that area.

What's going on here folks? Am I on to a new variety or varieties, by chance??

Thanks

The only way to tell for sure is if we do an overlay and check the mintmark position and other markers. One thing to consider is that some coins have so many good markers that we just plain can't list them all. In this case though, I agree that the die crack on the head should be a primary marker.
It is possible for it to be a new variety as well, and a rather significant one for the date. We have over 150 for this year already, so why not another one?
Basically, that's why Chuck and I are here. If you choose to let us attribute it for you, we can do overlays, confirm or eliminate like matches, and add it as a new variety if necessary. Right now, I just can't tell based on just the pictures posted.

Your Example looks to be almost a VLDS example. If you could get some images of the date and mintmark area, I could do an overlay.

After Looking closer to your images and comparing. I noticed Something.

Are they from the same die? What do you think? Click below to get the answer

An update on this post. I received the two coins from coppersleuth and did a comparison and overlay. They both are indeed 1960D-1MM-003. The disparity of the strength of the secondary mintmark was primarily due to die state. The reverse die was changed, so reverse markers listed in other books were not present.
A very prevalent obverse die marker (a large die crack above the ear), was identified and pics added to the site for the applicable die state (LDS).
Thanks Jim for giving me the opportunity to examine and report on the coins.
