Häufig gestellte Fragen
What is the Sheldon scale?
The Sheldon scale grades coins from 1 (Poor) to 70 (Perfect Uncirculated). It was developed by Dr. William Sheldon and is used by major grading services like PCGS and NGC.
What is eye appeal?
Eye appeal describes the overall visual attractiveness of a coin — including color, toning, and absence of distracting marks. An exceptional coin can grade higher than its technical details suggest.
Is this a substitute for professional grading?
No. This is an educational estimate only. For official grading, submit coins to PCGS, NGC, or ANACS.
