Things You'll Need
Instructions
Gently rub the coin to clean off any dust or other residue. Use the camera lens-cleaning cloth and rub each side in a circular motion.
Identify which type of coin you have, depending on the date and the description.
Visit the Coin Community Family website and, in the section for Large Cents, read over the grading standards (under "Facts") for whichever variety of large cents you have.
With a magnifying glass, follow the guidelines to grade your coins. Generally speaking, the dates and other lettering need to be clear enough to identify to warrant even a "good" grade. Other grades are very good, fine, very fine and extremely fine.
