Doubled date on a 1987 proof cent?

I know that the first step when asking about a coin in your possession is to post a pic so I must apologize. I will post a picture as soon as I can borrow my roommate’s digital camera.



My question however doesn't need a pic. I was wondering if anyone has come across information or pictures of a doubled date 1987 proof cent. The mint mark also appears doubled but the date is more prominent. The 1987 and s are both shifted to the north and west. (Assuming the head is north and the neck is south.)



I can't find any reference to an error of this sort for a proof cent of that year. I did locate info and pics for the d error but as I said mine is a proof.



Hope to post pics but tomorrow. Thanks.

Every 1987 cent I've come across has been VERY poorly minted. Its like someone beat all the mint employees with the ugly stick that year and it transfered to the coins. That being said, I'm curious to see the picts when you get the chance.

 

Here are the pics. I had some trouble getting the reflection down so you will see some reflection shading around all of the numbers. The point of intrest that I am trying to show is the 7 and s show a larger area which apears raised from the field. This area appears to be a doubled image.

Any and all opions on this matter would be apreciated.

 

First guess is a over polished die, or perhaps a planchet plating defect. Second guess is a triple struck proof....the first strike being a bit south, the following 2 strikes being on target. Going to leave this one to MikeDiamond though

 

Thanks Dog, You pretty much summed up What I thought. And Just like you I said I was hoping Mike would take an intrest.

 

It's very hard for me to draw a conclusion. The highly polished field of a proof coin can lead to the appearance of doubling where none exists. If the extra border is indeed raised, it could be machine doubling (strike doubling). The fact that both the date and the mintmark are affected and affected in the same manner and direction would be consistent with machine doubling. However, I don't really see any flat shelving. The surface of the coin appears a bit lumpy, so it could be a mild case of blistered plating. This is not unknown in proofs. I doubt it's die deterioration doubling, as proof dies are retired after a few thousand strikes. But I can't eliminate the latter possibility. Sorry I couldn't be more helpful.

 

I was able to view another 87 at my dealers today and it looks perfect. Sorry fine, for those that don't believe in perfect.

Is there some where I can send the coin to have it reviewed by experts?

GDJMSP often recommends contacting CONECA and Ken Potter. No complaints so far I believe you can email them the pictures first, if they don't have a clear idea, the will request the coin be sent in.

 

Lawdog-

I looked and looked but I could not find contact info. If you don't mind leading a horse to water where exactly do I go on the site.

 

thank you

 

Hi,
I've seen many coins that appear to be doubled this way. It is a result of metal flowing over the surface of the coin. The copper plating sometimes seems to be "pushed" around the details during the strike giving a rippled, doubled look around the lettering and numerals.
Have Fun,
Bill
