After some majorly slow Dial-up research,

and a small celebration with my friend Mr. Beam

. I have learned a little and can refine my questions.
1. K3... I think this refers to the location of the cud as viewed from the obverse. Mine would be at the 3 o'clock position from the obverse. This is my guess based on other cuds I have looked at this evening.
2. Attribution is for Varieties (1999 Lincoln Wide AM), not Errors (cud/lamination)...
3. Information abounds for Varieties and is sadly lacking for Errors. See #1.
4. CONECA offers an Error Examination service, which I don't need for this coin, I already know what I have. They also offer an Attribution service for Varieties. Both are available for non-members at a reasonable cost.

1. Anyone have an idea of the value?
2. Will PCGS/NGC/ANACS grade a coin with a cud?
3. Should I even bother with grading?
