What is wrong or right with this 1853-C Gold Dollar?

If this definition is used, then I have to be careful not to use die break and die crack interchangeably as I do now. A die break would be the terminology I have heretofore called an internal CUD.

I would not expect any luster absent surface contact with the dies.

 

Dadgummit. Mixing golf up with coin science.

 

Thanks!!!

 

But if the lamination broke off after the coin was struck...the newly exposed area would have never contacted the die. So then...that area would have muted luster, right?

 

It would have NO luster in the area beneath the lamination which broke off because it never contacted the die. If by some chance you found the lamination that broke off, it should have luster.

 

I don't know how long each of us posting has been collecting or the depth of our numismatic experience/education. Unfortunately, some of us like to stick to our old beliefs in the face of solid evidence against it. Thus, misinformation continues to circulate. I suggest anyone posting who has not taken an ANA or other seminar course or who has never read the several excellent numismatic books dealing with grading such as the PCGS Grading Guide and the introductions to other grading guides DO SO IMMEDIATELY.

Can any member here tell Marshall and the rest of us WHY A METAL SURFACE under a lamination or one that did not touch the die HAS LUSTER?

BTW I always call the squiggly cracks on a coin DIE CRACKS - it is an old habit. They are more properly called DIE BREAKS because they resulted form a break (crack) in the die.

 

My guess is for the same reason as the area has lettering and other details...the imprint from the die gets pressed well into the coin. Luster is caused by the smoothness of the die which would be imprinted deep into the coin. So luster should be present.

My question is will that luster be muted at all as the surface under the lamination was deeper into the coin and therefore not imprinted as well.

 

Luster is a reflection of light from a surface. ALL METAL has luster. Yes, the luster will be muted on the original surface of laminations and weak strikes. Buffing will usually increase the luster on metal. Polishing will always increase it. Mint luster is a numismatic term for the luster on coins.

 

Ok. That answers my question. Thank you.

 

Hey Doc,

The next time you look at a spit covered tooth in a patient's mouth it will also have "luster" from the reflected light.

 

Show me a single example of LUSTER outside of a striking surface. It's like surface tension below the surface of water.

 

Look at your greasy forehead in a mirror.

 

Wouldn't this definition say that even a Poor-1 slug also has luster? A piece of paper? A rug?
