Coin Grading Scale
The Sheldon scale (1–70) is the universal standard for grading coins in the United States. Understanding where your coin falls on this scale helps you buy and sell with confidence. This reference covers Mint State, Proof, and circulated grades.

Mint State coins have never circulated. They were struck for commerce but went directly from the mint into storage or collections. The MS scale runs from 60 (heavily marked but uncirculated) to 70 (absolutely perfect). Coins graded MS-65 and above are considered Gem quality and typically carry meaningful premiums over spot price.
Proof — PF-60 to PF-70
Proof coins are specially struck using polished dies and planchets, producing mirror-like fields and frosted devices. They are made exclusively for collectors, not for circulation. A Deep Cameo (DCAM) designation indicates strong contrast between the frosted devices and mirror fields — the most desirable proof finish.
Circulated — AU-58 down to PO-1
Circulated coins show wear from use in everyday commerce. The degree of wear determines the grade. About Uncirculated (AU) coins have only the slightest wear on the highest points; Good (G) coins are heavily worn but still identifiable. For bullion coins, even heavily circulated examples retain most of their precious metal value.
Strike Types & Special Designations
Business Strike
Standard coins produced for general circulation. The most common type.
Proof Strike (PF)
Specially struck for collectors using polished dies. Mirror-like fields, frosted devices.
Specimen Strike (SP)
Early collector coins struck with care but not to full proof standards. Satin or matte finish.
Matte Proof
Proof coins with a sandblasted or acid-treated finish rather than mirror fields. Common on early 20th-century U.S. issues.
Deep Cameo (DCAM)
Strong, heavy frost on devices contrasting sharply with mirror fields. The most desirable proof finish.
Cameo (CAM)
Moderate frost on devices. Less contrast than Deep Cameo but still desirable.
