Instructions
Check for blemishes. If the cent is free of blemishes and wear, it can grade as gem uncirculated if it has a full red color. If the coin has more of a brown tint and is free of defects it is considered choice uncirculated (MS-63).
Look at Lincoln's cheek and jawbone. If there is only slight wear, the coin can grade as uncirculated (AU-50). With a lot of wear on Lincoln's face, the coin should be considered in very fine (VF-20) condition.
Examine the wheat heads. Heads that have been well worn will downgrade the penny to very good (VG-8) or fine (F-12). If there are no worn spots on the wheat heads, the coin can grade very fine or higher depending on the condition of the rest of the coin.
Check the condition of the date. Only if the coin is well worn will you have trouble reading the date. If the date is not clear, the penny cannot grade higher than good (G-4).
