How to Use the Coin Value Tables

These tables show estimated retail values for each date, mint mark, and variety across the most commonly collected grades. Here’s how to read them.

Sample Table (Lincoln Wheat Cent)

G4 VG8 F12 VF20 EF40 AU50 MS60 MS65 PR65
378 652 943 1,213 1,325 1,507 2,755 11,565 –

Understanding Each Column

G4 → PR65 (Grade Columns)
Estimated retail values in the most commonly collected grades on the Sheldon scale:
  • G4 – Good
  • VG8 – Very Good
  • F12 – Fine
  • VF20 – Very Fine
  • EF40 – Extremely Fine
  • AU50 – About Uncirculated
  • MS60 / MS65 – Mint State (Uncirculated)
  • PR65 – Proof
A dash (–) means pricing data is unavailable, the grade is extremely rare/non-existent for that issue, or (on modern coins) the piece is worth face value in that grade.

About the Prices

Values are estimates of what a collector would typically pay a dealer or another collector. They are based on long-term tracking of catalogs, dealer lists, eBay and Heritage results, our own marketplace, and live precious-metal prices for silver, gold, and platinum issues.

For the most recent years we use running mintage totals from the U.S. Mint until sales of a product end. Once a product is discontinued, the final cumulative figure becomes the official mintage.
