From the beginning NGC focused on only one objective, a standard of consistent and accurate grading. The knowledge, integrity and dedication of its team of grading experts ensure you a level of grading consistency unparalleled among grading services. To ensure impartiality and accuracy, three numismatic experts evaluate each coin submitted for grading. A grading finalizer assigns a final grade and the coin is then sonically sealed in a protective, inert plastic holder. NGC offers several submission services to meet the needs of coin collectors and professionals. It is necessary to choose the option that corresponds to the value and category of coins you are submitting. One of the valuable services offered by NGC is the attribution of coin varieties. NGC’s comprehensive written guarantee of grade and authenticity covers all grading tiers described there.
