1970 S Double Die Cent ??

I found this the other day. Can you give me some insight to its rarity and value.

Thanks

What that looks like to me is a case of machine doubling; damage after the strike, due to die bounce or chatter. Everything I've read says it is quite common, and actually reduces the coin's value. Some folks'll probably disagree with that.

 

If it was a double strike, wouldn't the majority of the coin be doubled? Just curious, so I'll wait for the resident experts to weigh in

 

Thanks for the replies people!

Yes I wondered about that also. I can't find any doubling on the coin other than the date and mint mark.

 

The 1970-S double die which is listed in Breens #2255 shows doubling on the date ,MM and Liberty, What you have maybe a variation of this coin type,, if your coin does not have doubling on Liberty,
Either way an in Person examination for your coin is recommended.


Your coin does not look like machine doubling to me,,

Here's a LINK to a site with TONS of great error info. Ken Potter is a wealth of information, and even runs his own ebay store. I don't know for sure, but I believe he even checks into this forum from time to time.

Oh, before I forget, the CONECA website is another excellent resource. Here's the LINK

 

Here is an excellent article by Ken Potter that discusses this as well as many other types of doubling. Specifically, look at the first example. I have a '57 D cent that has almost the exact same doubling as your '70 S.

This looks like machine doubling, not a doubld die.

 

Well since it isn't all that rare I think I'll just put it on Ebay listed as a "doubled date 1970-S Cent". Thanks for all the help.

 

Your cent is a classic example of strike doubling. Check out the sticky thread at the top of this form on die doubling...

 

After reading quite a bit of literature on the internet I now understand about master dies and working dies and how doubled die coins are created.

Also, I was not aware the mint mark was punched into the working die after the fact. I am assumind the date is part of the master die.

That still does not explain how after the die is set in place and by a "bouncing/chattering die" only a small part of the coin is doubled. Wouldn't the metal on the coin or die have to stretch or bend for this to occur.

 

Again I can't visualize only a small part of the coin's metal being pushed or scraped off to the side. Since the die is low enough to push the date and mint mark to the side wouldn't it then also push aside any metal or coin details that are as high or higher than the date and mint mark. I don't think the date and mint mark are the highest details on the coin.

Just trying to visualize this whole thing.

jtwax, is a very knowledgeable person on this type of thing, if he says its strike doubling then that is what I would believe, I didnt think it looked mechanical based on the lower loop of the nine and the zero, but I submit to jt's opinion.

Jtwax, Metalman and others,

Don't get me wrong. I am not disputing anything you say. I believe you when you say this is strike doubling. But being an engineer mentality I am trying to visualize the mechanics of the processs that causes this and there are some holes in the explanations. That's not to say I don't believe the explanations. I just can't see how such a small part on a disk of metal can be pushed aside while the rest of the disk remains in tact yet everything is on a horizontal equal plane.

 

Amazing !

I have only a regular strike of that coin.

 

I understand what you are thinking and I have thought the same as you. I wish I could explain it but I can't. I have also seen the center design doubled but not any of the wording.
If you figure this out please let me know!
I also found a 1970 S just like yours the other day, so we are in the same boat.
Here is another link you may not have read yet.

Digger,

Yes I saw that site and the pictures there really allow you to see how the metal gets pushed aside. I think now I at least have some elementary skill at distinguishing a double die from a strike double. But the actual mechanics of it are driving me crazy. I'll just keep on looking for the answer.

 

I only popped in for a minute to provide this link for you. I think after reading it you will understand a great deal more.
