HI 1972 P Is It A Master Die Doubled Die?

Definitely need some clear, close up pics of the obv and rev. That 2 does look interesting to say the least.

Slight thickening in motto, I think. We'll need much better exposed photos with higher resolution on the devices in particular and if it is a DDO will need field photos as well to confirm whether or not it's a known minor die.

Someone else just yesterday posted a '72 cent with the same question, but that was a 'S' minted coin with the same appearance. So did the mint use one master die for all the mints? Here it is: http://goccf.com/t/467049
So yes the doubling on the upper curve of the 2 is hub doubling - you need to look at the tail of the 2 for the DDO.

That link looks familiar, John.

Your terminology is a little off, "hub doubling" is what you want to find. This is when a working die has doubling created by a working hub striking the working die incorrectly. The doubling we see here comes from the doubled master die, which was used by all the mints, so it can be seen on P, D and S coins. I think sometimes people get this mixed up with a "doubled hub" which is not the same thing as "hub doubling".

Hi, up close pix of IGWT, LIBERTY and full date etc. As you can see the coin is not the typical MDD as shown on Doubleddie.com or like the 1972 S ( link ). May be some Die Deterioration going on IGWT and LIBERTY. I see no doubling in these pix except for the 2 in the date. Tell me what you think. Thanks, Frank B.

Hi, Thanks. I had a feeling it was a MDD coin but I had to make sure. Thanks, Frank B.

Hi, That was the point I was trying to make. I can not find a link to show this particular doubling as MDD. Let me know and Thanks, Frank B.

Not sure about what is happening with IGWT. That being said, what is going on with the date I feel is just part of the design. I have a side by side pic of yours, a 72 P that is not from the doubled master and jipa's, from the other thread, that is a 72 S that is from the doubled master. The fact that what we are seeing in the upper part of the 2, is on both coins, leads me to believe it is something that is just in the original design, from the Galvano. See what you think.
