I had some coins posted on another coin site and they said there were PM marks

I had some coins posted on another coin site and was told by several of their site experts they were no die errors but only post mint errors. I thought I would post about three here for other opinions. Thanks. New to this site and loving it.

There is no such thing as post mint errors. It's either a mint error or post mint damage.

 

The picture quality is too poor to tell for certain. If the lines are recessed into the field, they are scratches, if they are raised, it's probably a die crack/break. Note that scratches can display displaced metal (raised) on the sides and that can look like a die crack.

They look like scratches in the pics, but can't be sure.

 

As others have said, looks like PMD or post mint damage. Better pics would help. But I don't think they are errors.

 

If it’s raised, it’s a die crack. If it’s not raised, it’s PMD.
Can’t tell from the photos. Welcome to CT.

 

If the line is raised metal it could be a die crack or gouge. If the line looks like a plowed furrow with the spoils from the trench piled along it's edge, it is a scratch. If the lines are recessed into the coin and have no sharp edges or displaced metal rising above the natural surface of the coin, it or they are possibly strike throughs of a hair or thread. Strike throughs have no sharp edges.

 

In addition they said some toned Pennie’s I posted had been cleaned and toned not naturally. I disagreed. They were in my dad’s collection but I am sure they are more expert than me. Attached:

 

Thanks to all. Those are old pictures. I will try to get some better ones with my new macro phone lense. Those are not very good.

 

Die cracks are not errors.

 

2001 looks like a die crack to me, and a nice one!!

 

A die defect is a unique and unintentional flaw in a coin die and is created through excessive use or polishing of the die.[1] A die bearing such a defect is occasionally referred to as a defective die. Generally, and depending upon the magnitude of the defect, coins that are produced from these dies are considered error coins.[2] Also, the term encompasses a wide variety of design errors that were engraved into the die originally and were slipped into circulation before the incorrect design was discovered. from wikipedia here is da link

Die related defects are considered varieties, not errors. This includes doubling, cracks, and chips. Since a variety is caused by a die, it will be the same from strike to strike. Although cracks and chips can change size and shape over time, the changes are considered die states.

An error is a unique, one-off coin, such as an off center strike, or incomplete planchet.

So @Jaelus is correct.

Edit to add

https://www.ngccoin.uk/news/article...or coins,your coin is a variety or mint error.

 

Thanks for the education. I have new pictures that may tell more.

 

I do a lot of die error and DD mint errors. I have a lot. Is it worth the time researching these, and what does one do with them?

 

Yes, exactly. Die cracks can produce varieties, or at the very least can be used as die state indicators, but they are not errors.

 

rkennedy1945@gmail.comHere is another one. Any errors or die marks. What kind if so?

 

What appears to be doubling is actually die deterioration doubling from a worn die. The rest are damage from circulation.

 

So is die deterioration not an error but DD is? How do you tell the difference?

 

Die deterioration is wear on the die from many strikes. A doubled die is actually on the die and will show on every coin minted until it is removed from service. A doubled die is also a variety.

 

The Kentucky quarter is scratched, so not an error, but damaged in circulation. A die is used to strike or press the image into the coin. When a die cracks during use, the result is a raised line on the coin as the metal of the coin blank is pressed into the crack of the die, thus causing a raised line on the coin (finished product).
A doubled die coin has the doubled item at a similar height on the coin. There is machine doubling that looks similar to a doubled die struck coin but has a height difference (one image high and one low) of the items. It has a shelf like appearance to it. Machine doubling is common and has no premium. Look at pictures of a 1955 doubled die cent to understand what a doubled die coin looks like.
