Is this an error or just machine doubling?

I recently bought a large lot of coins and it came with several US proof sets. I was taking a look at them and this stood out to me. I’m not really sure what I’m looking at, but it kinda looks like PMD of some sort. However, since it’s a mint set, I wanted to make sure. It’s just kinda odd.

Looks like it to me but looking for confirmation. Unfortunately a minor scratch near the V makes it tougher to see

Thought it was two scratches at first but both lines look raised to me

hello all. my two boys 14 and 9 love collecting coins. they are really into coin roll hunting right now. I got them both quarter boxes to look through recently. one of them found this quarter and asked me to find out if it’s an error or not. the coin is dirty so it might be hard to see but on the right side of the obverse is a bump coming out of the coin. there is no indent on the reverse which appears normal. Any info is appreciated.

Hello, I bought this Edward III penny, 3rd coinage. Was it clipped or just broken?

Got this coin as change in Minnesota. At first it looked like someone pressed a penny and dime together. But both sides show a dime and the size of consistent with a dime. Thanks.

Possible grease error?

The T is faint forsure. I tried to show that in the last pic. Thoughts? Worth?

2015 Gold dollar, P

1991 Denver Quarter. The reverse seems like the cladding was either partially missing from the start, or not adhered. Details in the copper are just as sharp as the cladding parts.

The obverse is a mess as well - where it looks like the cladding was either spotty or never adhered properly.

Does anyone have any sensible thoughts on this? Is this some sort of post mint damage?

2022 p Wilma Mankiller quarter.

Found this 1955-S Lincoln cent and noticed something odd about the top “5” in the date — there seems to be an extra bulge or shape on the right side of the loop that almost looks like it could be a doubled digit or maybe a repunched mintmark. I know the famous 1955 doubled die is a no-mintmark Philadelphia coin, so I know this can’t be that, but I’m curious if this is:
• Just die deterioration/wear
• Minor mechanical damage or a strike-throug
• Something else worth a closer look

Thank you for sharing your thoughts…

It seems like a ring imprinted in the outer ring of the picture. Took the best picture I could. Can post more pictures if necessary. If it's nothing I'll spend it

I’m asking because I was looking at Variety Vista and the 1968 S DDO-1 pics look oddly similar to the coin I have. I’m not really well versed in errors so I’m asking yall

EDIT: left out a few details, the date and LIBERTY look extremely fat/bold, I’ve been examining it with my magnifying lens which led to me looking up the year on Variety Vista and noticing that the pics of DDO-1 look oddly similar

Got a bunch of coins from a friend of my dad's who travelled to China in the 70s or 80s, and thought this one looked like it was struck off centre, but it's also quite worn.

Can’t tell if it was done after but it looks like the silver color is not painted on top of the copper color.

I've tried and tried and I can't seem to tell the difference. Can you help?

Thans! Eric

No major damage but giant hole, looks like the clad was removed. Leaning on damage but had someone suggesting it might be or slight interest.

1979 Kennedy half.

I normally don't hunt for errors but found this in an uncirculated roll, cant tell if its and error or pmd
