Greetings! Please take a peek at these pics from a 1970-S proof set. The small date Lincoln exhibits some mild spread on the 0 in date, plus on some of the letters in the motto. Most visible on the TRUST. I'd say the "0" spread in date seems legit. On "TRUST", while I realize there appears to be some strike doubling, there does appear to be some legit spread in the letters, especially "U" and "S" in TRUST. But I am unable to find any of the current coppercoins pics which match up. Any help is appreciated. I was hoping it is a "new" one!

Hmmm! Seems that no one wants to answer this question.
I am inclined to believe that it is machine doubling. I do not see any telltale notching or distorted extra thickness on any of the design elements that you have shown.

I'm curious what this is also? Very nice pics btw. I am also curious to know how common machine doubling is on proof coins?

Very common! Because the proofs are struck more than once so many of them have very flat looking machine doubling.

Thanks Ed, I'm still a little confused on the difference in the two types of doubling. If the coin is re-stamped, wouldn't that be normal doubling as opposed to machine doubling?

Do you mean the split along the centerline of the lower areas of the U and S?
I'm thinking the nip on the top end of the S is machine doubling.
So maybe the coin has both?

I'll put in my 2 cents:
The date has the crease on the uppermost part of the "felief", as does the other letters shown which could mean some form of hub-doubling.
The other pictures also show the definite shelf-doubling, (MD), and the flats are all in the same direction,and same degree of lateral
displacement, or movement.
Ed asked if both conditions can exist at the same time?
IMHO, the answer has to be yes.
FWIW, I have seen the same thing, bt not exactly for the same reason in the Working dies, and the working HUBS, used in the Canadian Large cents. Obviously, NOT from the same cause. The Engraving procedure was by hand, rather than machine, as is used today.

I agree that this is a doubled die, looks to be class V. It also shows machine doubling.

You are correct - the separation lines at the highest point of the relief is the doubled die. The flattened stuff to the right of most of the characters is machine doubling.
