What is Coin Grading?
Uncirculated coins have different grades as well, depending on how carefully each coin was made, handled, and stored. Some uncirculated coins have heavy marks caused by contact with other coins during minting or storage. Other uncirculated coins are nearly free of such marks. The coin in the best state of preservation will almost always have the greatest value.
An added benefit of PCGS coin grading is the PCGS Guarantee of Grade & Authenticity. This cash-back policy ensures the accuracy of the grade assigned to any PCGS-graded coin, as long as it remains in its tamper-evident PCGS holder. Read the policy in its entirety through the link below.
