Most Valuable Liberty Bell Half Dollar: The 1964 Double-Date Proof

The most valuable issue in the Liberty Bell half dollar series (1948–1963) is the 1964 Proof struck for the 200th anniversary of the Declaration of Independence.

Key Features

• Dual date 1776–1976 on reverse
• Only 2 million proofs minted (lowest mintage of the series)
• Struck at Philadelphia Mint during a special ceremony at Independence Hall

Value

High-grade examples (PR67+) can fetch thousands of dollars. Condition, cameo contrast, and certification greatly affect price.

Regular circulation strikes from 1964 do not carry the dual date and are far less valuable.
