Just shot these and thought I'd get a few opinions on what you think. And is there any unwritten rule on size or definition on double MM's.
Unwritten rules? I think that the rules are very clear these days. So many variety books exist on every possible series. I however love the varieties for the most part. I think it is one of the most interesting part of numismatics. The study of how and why these occur. It can teach you about the mint engravers and the minting process.
Interesting coins Thanks for all the suggestions... But what I was looking for was a little input on the pic's not my lack of education or where to find it. But thanks anyway..
Well the cud looks good, the rpm's look good. The doubling is a little blurry in the pics. Is that what you were looking for?
If you look at the 1957 Lincoln in your picture, the 9 is filled. That is a cud. A cud is a foriegn piece of metal that has been struck into the coin.
I believe that's the definition of a strike through? I thought a cud happened when a piece of the die broke, leaving a gap or void area, where the metal ( following the path of least resistance) flowed. Cuds usually have a corresponding weak strike on the other side of the coin directly opposite the cud.
Actually, the coin with the filled 9 in the date is rather a "die chip". A CUD is a rim - to - rim die break (where part of the die actually breaks away). It will only appear on the outter edge of a coin. When the die has cracked and not yet broken away (from rim to rim) it's called a "Retained CUD". As far as your pics go you are on your way. A couple of the RPMs appear to maybe be strike doubling rather than an actual RPM, as well as the two number 7's. The doubling on LIBVERTY is too blurry to tell...
What about the Washington Quarter at top?? Is that a strike through with maybe material still present. It does appear to be raised?
