2006P-1DO-001 or 013 or 015 or 020 or all of them ?

[MorgansRmine]

These pictures are all from the same coin. While I can't find all the die markers to match one number exactly, I can find some of the die markers for all four of the coins in the subject.

IBERT of liberty.

Scratch from 2 to jacket.

Polish lines of left corner of building.

Crack off left planter.

Eye and forehead.

Nose.

Ear. On the eye & forehead, nose and ear, I'm not sure the markers are there for the 001. Next 3 pictures show die markers for the 013.

Die chip on second column.

Die chip on 11th column.

Die scratch above UNUM.
Die marker for the 015.

Gouge or die dent near rim.
Die markers for the 020.

Die crack from rim through middle of E.

Die scratch between bottom of B & U of pluribus.

If anyone makes it thru all this reading and pictures, where do I go from here ?

Great pics of the markers! It made that easy to attribute.

It's 1DO-020

Check out the match on the rev crack on the E, it has the same exact shape, sort of a blob going in the center crosslet, slight curve through the vert area, same little bumps as it crosses to the rim.

It is that same die.

The reason you see some of the other markers for other ones is many of the markers are in places that tend to get cracks or blobs. If you look close they're slightly different shapes.

Ed, my thoughts exactly when I first noticed the crack in the E. But this coin still goes against the grain as each variety being able to be traced to a separate die. My thinking could be wrong here. What are the chances of having 1 or more die markers for all four of these varieties. My thoughts are this coin is related to one or possible all four of these varieties, just a diferent stage in the production. Open to any opinions or readjustments in my way of thinking.

A lot of the markers you see are weak points on the design elements that tend to crack the die with repeated strikings. As Ed mentioned, they may be very similar, but closer examination will show that they are slightly different in direction and/or strength. This is not unprecedented either. Cents minted since 2000 seem to have a lot of die cracks on the forehead. The 80's saw an abundance of die cracks from the corners of the memorial to the rim. Coins of the 60's always seemed to have die cracks on the 12th column and right cornice. 1957D coins had clogged letters (especially the B of LIBERTY) and coins in the 50's also had many, many BIEs.
So, in retrospect, the different coins having close to the same markers is not that rare, but considering the pure amount of dies used during any one year, and the fact that 2006 produced billions of coins, it is not too unremarkable.
I hope this helps a bit.

Those die cracks can be lifesavers, at times. It also helps to have themarkers, "marked with a pointer". Some of them, one has to try to read minds. LOL When you are working with MM, then it gets to the point that a lay-over , (overlay) is the only way to be sure, when there are several MM's is so close to the correct die position.

Bob, I sent you a PM.

Maybe I should add:

Sometimes you might find a variety that is or looks the same as another.
Start with the doubling before looking at markers.
If the doubling matches look for the markers. (similar to RPMs where you look for spread, location then markers last)

Even if no markers are there you might have an earlier one from the same die pair. I'm sure with so many similar listings there could even be something listed as 2 different varieties but it's unlikely.

So to your original question, a coin is from one die pair but coins from that die pair can show up missing markers if it's an earlier die state. Some markers like gouges might be there from the start. The markers like cracks grow as the die gets worn. One way they can tell them apart is if for example you found one that looks like 1DO-020 but it has no crack then it must be an earlier die state or a different die pair. If the coin has similar doubling and no crack but it's a later die state then it would be a different die. Then to add confusion sometimes they swap out a reverse die, if the reverse on this 020 fell apart they might put a new rev die with the same obv die.

If you look at well known DDOs you will see more documented die states and stages because more examples exist to be studied.

Hope that helps

Maybe someone can add more.
