Has anyone seen machine doubling or any other errors on proof sets?

There are numerous errors. You can google "No S Mint Mark" for results on various years where certain denominations were minted and included in the proof set with out the S mint mark. Then you have die varieties such a Type1 and Type2 S mint mark. Commonly called Filled S and Clear S. I have a few silver brown pack Ikes that are known die varieties from peg legs to doubled dies. I just recently sold in one of my collections that I have had listed in the classified section here on TNet a doubled die '66 Kennedy Half in the Special Mint Set packaging.

Bought 5 sets today at pawn shop for 10$ each 1968 69 73 74 75 seen a gouge in the obverse field on 69 penny broke out the loop to reveal doubling on a lot of letters?

Proof coins are all struck twice to bring up the sharp image, any movement between strikes will cause doubling,

Thank you for your input and help, theirs allot I don't understand about the process of minting a coin.

Any movement between strikes will cause machine doubling, not true doubling.

I'm selfish I want a 69 s d.d especially a proof. I should be glad that I were able to purchase what I got, a couple 40% half's that are proof. [emoji4]

Which 69s are you referring to?

Which 69s are you referring to?

Maybe the 1969-s fantasy proof DDO?
(OP- the coveted '69s DDO is a regular business strike, not proof)

I sold a Proof Eisenhower DDR for $3,600 earlier in the year. I found a DDO proof '54 nickel a month or two ago.
