How normal is for proof cents to exhibit strong machine/strike doubling?

Musky1011 · January 30, 2015 9:13AM

Well they are double stuck

LindeDad · January 30, 2015 9:30AM

Modern one's are double plated to.

There is one on the bay as has some crazy machine doubling as the shelves are all flat. I just have not seen a proof this bad before I will grab some images in a little bit.

added pic and changed title.

Sweet !!!

i would think it's not normal by any means
but a general lack of interest exists
no real premium will most likely ever develop...hopefully i'm wrong

I have several 1970 proof pennies that have this machine double strike. There are also a lot of 1962 and 1963 proofs that look this way too.

1962 products more proofs DDO(s), then any other year for proofs

Proofs are struck at least twice. If there is slight lateral movement of the die between strikes you will see the shelf on the side of the design features. It's not true machine doubling which happens with a single strike during mass production of business strike coins. I've seen this often enough that I don't consider it to be anything special although I'm not surprised to see eBay sellers hyping this to uninformed potential buyers.

While not common, I have seen it on a few proofs...usually not quite as obvious as this one.... Cheers, RickO

This is a 70-S and the issue above the U is being called a clash. The line does go through the R at the top.

I have seen quite a few San Francisco proofs (1968-on) with a bit of motion between the two strikes.

I have seen it before my self but was wondering how often this occures as I would think this would be a reason to reject the release of the coin. It is supposed to be a "perfect proof" after all.

i'll start a thread to see how many show up...."show your strike doubled proofs" and we'll see
strike doubled proofs

I am not sure that we should blame the two strikes per proof coin for the doubling. The second strike if slightly off might tend to snap into alignment.

It happens in die making. Class III double dies can also show pivot and rotational doubling due to the failure of the second die to line up with the first image. Non class III doubled dies show much less doubling.

1970 quarters show many examples of this.

wont go so far as to say it is common but it happens enough on all denoms from what ive seen.

It happens frequent enough that the interest in them is usually limited to the finder of it and a very limited few others.
