Question on a 1969s cent

Could this be a doubled die? Obverse of a 1969s cent. I see no other (doubling?) anywhere else on the coin.

Looks like strike doubling.

No doubled die. Keep looking

 

double die vs. double strike?

What exactly does the expression "double die" mean to a coin?

I have a background in punch press, deep drawn die fabrication.

In my former metal stamping and drawing world, double strike would infer two hit from same tooling (usually from a punch press) - one operation completed or attempted twice.

Again, from my days in and near the metal shop, double die would be two dies, either as two separate operations, or perhaps in a one-two progressive type of operation. In this example, the first operation die would be less formed than the second.

Thanks for any input?

 

You are exactly correct. There is no such a thing as a 'double die'.

Coins are not stamped they are coined, a completly

Coins are not stamped they are coined, a completly different thing.
In stamping the metal is forced (or punched) around (or by the stamp) - in coining there is three dies, obverse, reverse and collar and the metal (planchet) is forced into the encuse dies, remember the die is negative or encuse, (in reverse) and the coin is a positive.
The term "doubled die" (not double) refers to the die that has been hubbed more than once in an incorrect postion thus having some duplication to the lettering, words, or images on the die itself.
Hundreds, (or thousands) of dies are needed each year. Each die (before) about 1997 for cents) is put in the hubbing press and does not recieve a full impresstion the first time. The die hardens and must be heated again and repeated some times multible times. If the die is postioned in the hubb slightly adjar (or in any way not in the original position) in the hubbing press it will recieve overlapping design elements.
The coins struck from these dies are called "doubled die coins" but what we are really referring to is the die that struck the coin, ie: "doubled die".
A doubled die is an "variety" because the mint most likley knew about it and let it go anyway, (in production) but more importantly because it can be traced to that very die. A double stuck coin is an error and is random and not traceably to any one mint manufactoring process other than a mistake.
In all candor this is short version of the subject and over-simplified. I left out about 90,000 words of further clearification that is an important part of the subject. I hope this helps you.

 

Answer to original question is ....No

 

You've got a fairly good grasp on it.
Double Strike - Coin was struck twice by the die(s)

double die - coin was struck by two dies (all coins are struck by two dies, one obv one rev.) A few types of coins were struck by two dies with the same design one being raised and the other incuse. Basically making the coin by embossing it. Some ancients and some French Emergency tokens were made that way.

Doubled die - note the second D, very important. Coin was struck from a defective die that had a doubled image on it. Struck from a doubled DIE! Whe the die was made the design was pressed into it, it was softened and the design was pressed into it again but not in the exact same place. This caused a doubled image to be ine the die. Coins struck from that die will also show the doubled image.

 

Informative posts like this remind me why I visit the CT forums.

Since this post started about a 1969-S perhaps I can post the 69-S I just received in the mail. I got it from the other-other-Frank by mail order.

 

Nice!

 

Different looking cud, especialy the part under the date.

 

Can I see a Picture of the coin's reverse?

Thanks,
Bill

 

It is a known cud. It is LC-69S-04. I may have a photo of the reverse on my other computer. For the time being, here is a nicer photo of nicer example.

 

Here it is-

 

Nice one!!!:thumb:

 

Hi,

I know it's a CUD It's a nice one. I wanted to point out the weakness that will be on the area of the reverse that corresponds to the raised metal on the obverse so others can use that information when identifying other CUDS.

Have Fun,
Bill

PS: I just saw the image of the reverse! Notice the weakly struck area that is a diagnostic of a true CUD.

Thanks,
Bill

 

A large CUD too!!dd:for 1969 too

 

The 1969S DDO and The one with Strike Doubling look very much alike,The key is the MM!
