There are 11 different grades used to describe uncirculated coins. Differentiation of these grades requires the trained eye of a well-seasoned collector or dealer. Some coins are unknown in uncirculated condition or in the upper levels of the uncirculated range. This contributes significantly to the value of some coins. Fortunately, one point difference between the grades of most coins falling in the lower half of the uncirculated range often makes little difference in a coin’s value. However, if your coin appears to fall in the upper levels of the uncirculated grades and is a candidate for carrying a hefty price tag, it is best to consult with a professional or have the coins graded and encapsulated by a grading company.
Grading uncirculated coins takes dedication and experience but is well worth the time to learn if you intend to grade coins for yourself. Do not be afraid to visit shops and coin shows to study coins that have been graded by professional grading services or to consult with a knowledgeable dealer. Most importantly, arm yourself with the proper books and study them over and over. Start with our recommended book list and check your local library.
