Coin collectors strive to obtain the best examples of every coin they buy. And the best is perfect Mint State 70, or Proof 70. Since coins are graded on a scale from 1 – 70, 70 is the highest possible grade. The greatest collections from the past consist of top-graded coins. The greatest collections of the future are being built right now—with Mint Sate and Proof coins graded 70 by Numismatic Guaranty Corporation (NGC) and Professional Coin Grading Service (PCGS).
