Page "Coin collecting" Paragraph 57

When evaluating a coin, the following — often subjective — factors may be considered: 1 ) " eye appeal " or the aesthetic interest of the coin ; 2 ) dents on the rim ; 3 ) unsightly scratches or other blemishes on the surface of the coin ; 4 ) luster ; 5 ) toning ; 6 ) level of detail retained, where a coin with full details obviously is valued higher than one with worn details.

If the coin is judged favorably in all of these criteria, it will generally be awarded a higher grade.
