IHC Help

Found this 1884 IHC at the coin shop yesterday.

Doubling covers entire "UNITED STATES OF AMERICA"

Does anyone know of a variety listing for this coin and value?

It looks like Longacre Doubling....not sure but I don't think that adds any value....I have one that has in on the ONE CENT...

I suspected Longacre Doubling but the doubling being so prevelant on both sides of the device made me wonder.

 

ok....new term. Longacre doubling = ?

Best I can find is Hob or Punch Shoulder Outlines which means as much to me as longacre doubling. I can see what it is, but what causes it?

Thanks

 

Hi Lawdog

Longacre doubling in my understanding would be the equivilant to what we commonly call strike doubling or Mechaical doubling today, but being extremely common on the Indian cent it was named after the designer James Barton Longacre .

For what reason it occured so frequently on these cents is something I cannot answer !

Ahhh...ok...Thanks

 

Longacre Doubling is not Mechanical Doubling - it is doubling that in most instances originates in a working hub. Therefore Longacre doubling can be transferred to several working dies.

 

Longacre doubling is not mechanical doubling. Opinion is divided as to its cause. It seems restricted to 19th century coins. I believe it is rather common.

 

Ok ,Not Mechanical doubling ? Like I said that was my understanding based on what I find from you guys was bad information !!

If it is true hub doubling ,Then I assume the no added value is a result of the common aspect of it ?

Im not sure how Hub doubling would come to surround the devices like Longacre doubling does,, one of you guys care to elaborate ?

Thanks

It's not hub doubling (in other words, not a doubled die). One theory is that, in the preparation of a master die, each letter punch is tapped too hard so that the shoulder also leaves an impression. I have my doubts, but no better explanation has been introduced.

 

Thanks Mike

So the die being in its relatively soft state before annealing allowing the engravers die to penetrate to far ?

sounds reasonable, and certianly eliminates Mechanical processes of the press

sorry for posting ,what is now bad info on this topic.

Annealing softens the die. So presumably the punching-in of letters is done after annealing.

 

Hi,
This form of doubling is also very prevalent on nickel composition 3-cent pieces. As previously said, it is very common on Indian Head cents.
Have Fun,

I think it's called.Fatigue doubling.The die is wearing out.LDS.
