Niewmismatic Error Coins

Why My Coins Were Not Graded?

Why the grading company still charged me when they didn't grade my coins?

There are  ten different categories of "nograde" classifications currently in use by PCGS. If a coin falls into one or more categories, it will be returned unslabbed.

Planchet Flaw - Raised metal, missing metal, peeling metal and annealed planchets are just a few of the mint made flaws which, if large enough, will disqualify a coin from encapsulation. Grease in the dies, clashed dies, die cracks and die scratches are another story. The grading services will almost always grade coins with these problems, even if they are rather severe. However, if these problems detract from the coin's appearance, the services might lower the final grade by a point or two.
Altered Surfaces - The Coin Doctor strikes again! That mischevious devil tries to cover a coin's defect to trick the graders into a higher grade. A coin with altered surfaces has generally had a foreign matter applied to it. Currently auto body putty seems to be the substance of choice. Some coin doctors will frost (almost literally paint) the cheek of a Morgan dollar in order to hide facial marks or make them appear less severe. It takes a lot of practice to tell when this has been done, but a good tip-off is when the bagmarks on the cheek appear to be nearly as frosty as the cheek itself.
Scratch - Location is extremely important here. A half inch scratch on the reverse of a Morgan dollar between the denticles and the lettering will usually cause the coin to be downgraded a point or two. That same scratch across the cheek of Ms.Liberty will probably render the coin ungradable. If you were bidding on MS-65 Morgan dollars sight unseen, would you want to receive one where the first thing you notice is a half inch scratch in the center of the obverse? I didn't think so.
