This one looks like a DDD? There is a faint "something" south and west under the mint mark. I'm not currently finding a match on CC site. Thanks for your help.

that last photo also shows a doubling at the tip of the 9... could be Machine Doubling, but I'm a newbie, so I'm curious what others have to say.

I looked quickly, but looks a lot like this one. Try to match it up.

Jay(many#'s), thanks!! I think you found it!
Check out the die marks under the middle "E" leg. It's a match.
Thanks again

BUT..... Something Interesting! D/D south 007...but the D in my coin above has additional serif divisions west on the north and South Pole of D's vertical leg...if it matches with the south that's additional D's?

Even the tip of the nine matches to the 1MM-007, but there are no other serif divisions I see on that coin referenced on the CC site. Hmmm, any thoughts.

Maybe it's the same reverse but a different obverse? Or maybe a different die state? Coop...

Hi john, I Thought that too about the reverse BUT the obverse 9 is a match too...the bottom of the nine has that "extended" flat tail. Does the MM placement seem right? I think so...
But the "primary" D has those extra serifs.

Placement of the MM looks right to me anyway. Maybe your coin is an earlier die state?

Could it actually be a D/D/D? Hypothetically would that change the listing?

Here's the pic above zoomed in and in Black/White to better define the serif on the primary D.

On the CONECA Disk, they list three die stages. The Stage "c" shows a die chip on the "5" in the date. Yours does not have that, so it maybe a later stage of "b". The die gouges below the mint mark are not present on the stage 'b' on the disk. On all three examples the split serif does not show on the CONECA examples in the three die stages. So it might be contact mark? But it does appear to be 007 from what I can see.

The upper serif shows division near the coin. A top that it disappears into the triangular flat at the surface of the primary D. It may be too coincidental to be contact marks, don't you think? Opinions pls

That is a split serif. So it may/may not be from the same die?
