1972-D 2% curved clip Kennedy

[Shleppodella1]

I'm not sure if this is even a valid 2% curved clip. The clip looks questionable with the way the metal flows and scratches and even the heat sync marks but it looks smooth like it happened at the blanking machine.
The "T" in TRUST looks to have a split sherif. STATES looks like MD. The reverse left wing up by EPU looks to be doubled, as well as, the bubbles above EPU/stars.

In my opinion, we would need to see the obverse and reverse side of the clip.
With a clipped planchet, metal movement and the planchet itself moving during the strike is possible. The collar may not have a solid grip on the planchet. This means it very well may have other mechanical issues introduced during the stike as well.

Here is a decent writeup of a curved clipped planchet:

I see the full obverse and reverse photos now. It look good, the larger coins make the clips look so dramatic. I dont collect buy or sell many clips. But my is a 25% clipped Sacagawea.

Is TRUST doubled see the split sherif in 1st "T"?
I know the STATES is MD because of the shelf edges like you said but the 2 in the date is from MD as well that's how it got all wrung out and twisted looking I'm just trying to understand the process please and make sure there's only the 1 error of the 2% clip on this coin.
I haven't seen many clipped Sacagawea's nice.

In my opinion, when an error like this occurs, it can induce other mechanical issues/side effects as well, like machine damage. It can be evident on one or both sides of the coin.

My attempt here is to not become too complicated but...... we have a planchet issue here. That in itself is the blank that is a clipped. Then add in a striking issue, which offers mechanical damage which may have been caused by the planchet issue. It kinda makes sense.

Now, the possibility of a doubled die is questioned. That would be die related. One has to research all of this and see if it is, and whether it even resembles the documented examples.

If your concern is if it is a doubled die, then one would go to see if there are any listings for the 1972 D Half. There is just one variety. So, now its about where the doubled die would occur and what the documented look is. To me, its not a match.

So, whatever caused that one letter to appear like a possible doubled die was invoked by the strike. The 2 in the date is also odd.

BUT.... those above mentioned things are in very close proximity to where the clip is. I expect odd things to happen when a known condition is introduced into the strike.

No one can know precisely what happened with each coin manufactured at the mint. Some of it is a SWAG. That because we base our knowledge on experience, logic and the steps we need to take to look the coin over. There could have been a train wreck of planchets in the striking chamber or hundereds of different scenarios thatcintroduced the mechanical doubling.

The possible doubled die theory can be proven or debunked by normal attribtion steps. That typically does not change.... with a few rare exceptions.
