1972 P Unsure

[Rhubarb]

This 72 P has light separation on some letter's. I don't know if it is from a weak strike or from wear. There are visiable lines on some of the letters. What do you think?

David, It looks like MD, from the general shift of everything to the same direction.

I agree with Dick. This coin does have Master Die Doubling as did over 50% of all 1972 PDS cents.

Thank's Guy's.

Very Heavy die flow lines on it. The images are what we need to see. Good Job David!

I believe Dick was referring to machine doubling, not master die doubling. It's not machine doubling...it is indeed master die doubling. About half of all 1972 cents have the same doubling.

[Bob P]

I think that's what I already said above....that it was master die doubling. As far as MD and MDD, it is a point that we need to clarify. For MDD, some folks say Master Die Doubling, while others say Machine doubling damage. I assumed Dick meant Master Die, but I specified that in my response.

[Dick]

Bob, I have to go along with Chuck. I meant Machine doubling, not Master /die Doubling. I was not aware that MDD could produce a similar effect. This proves that I am still learning, so there is still hope, not much, but hope!

Sorry Bob, didn't mean to run over a statement with a statement.

Dick, machine doubling and master die doubling are completely different things.

Machine doubling happens during the strike of the coin. Die bounces, whatever, leaving the edges of some of the letters mashed down.

Master die doubling happens way up the food chain of creating the die. One of the initial pieces made after the design is reduced is the master die. The master die is responsible for creating a number of working hubs, which in turn create a number of working dies each. One master die can be responsible for transferring its design to hundreds of working dies. If there is hub doubling (a doubled die) on the master die, that doubling transfers directly down the food chain to all the coins under it. Given the sheer number of coins created by any one master die, they are very common, thus worthless as doubling.

If you look very closely at a 1961 cent, you're likely to find another example of master die doubling on the top of the OD of GOD. The O is usually doubled, and this doubling can be followed to the D. Nearly half of all 1961 cents are like this.

A bit off track but....

Just wondering if this particular die was also recut? The N of IN just looks like they recut it or something.

Thank you Chuck! That was very interesting, even though I had read about it somewhere???. I used a lot of magnification, and went back to see the photos again, only this time I was able to see a "rounded area", above the "crease lines in G-O-D. Yes, it is MDD, not MD. I appreciate all the help I can get!
