Understanding what makes certain 1999 Kennedy Half Dollars valuable requires knowledge of mint marks, condition grades, and special varieties that were produced during this pivotal year in American coinage.
Understanding the 1999 Kennedy Half Dollar
The Kennedy Half Dollar, first minted in 1964 to honor President John F. Kennedy, continued its legacy in 1999 with several distinct varieties. The 1999 half dollar coin value depends heavily on understanding these different types and their respective characteristics.

- Composition: Copper-nickel clad or 90% silver (proof versions only)

Mint Marks and Their Impact on Value
One of the most crucial factors affecting 1999 half dollar coin value is the mint mark, which indicates where the coin was produced. Each mint facility produced coins with different characteristics and mintage numbers.
Philadelphia Mint (1999-P)
The Philadelphia Mint produced business strike half dollars intended for general circulation. These coins bear a “P” mint mark located on the obverse, just below Kennedy’s neck. The mintage for 1999-P half dollars was relatively low compared to other denominations, contributing to their potential value.
Value Range for 1999-P:
- Circulated condition: $0.55 – $0.65
- Uncirculated condition: $5 – $50
- Pristine uncirculated (MS-67+): Up to $2,700
Denver Mint (1999-D)
Denver Mint half dollars feature a “D” mint mark in the same location as the Philadelphia coins. These business strikes were also intended for circulation and share similar value characteristics with their Philadelphia counterparts.
Value Range for 1999-D:
- Circulated condition: $0.55 – $0.65
- Uncirculated condition: $5 – $45
- Pristine uncirculated (MS-67+): Up to $1,750
San Francisco Mint (1999-S)
The San Francisco Mint produced only proof coins in 1999, making them distinctly different from the business strikes. These coins feature superior strike quality and were sold exclusively to collectors.
Proof Coins: The Premium Collectibles
The 1999 half dollar coin value reaches its highest levels with proof coins from the San Francisco Mint. These specially manufactured coins were created using polished dies and planchets, resulting in mirror-like surfaces and sharp details.
90% Silver Proof (1999-S)
The most valuable variety of 1999 half dollars is the 90% silver proof. These coins were struck in the traditional silver composition used for Kennedy Half Dollars from 1964 to 1970.

Clad Proof (1999-S)
The standard clad proof version was produced in much higher quantities, making it more accessible to collectors but generally less valuable than its silver counterpart.
Key Characteristics:
- Mintage: 2,543,401 coins
- Composition: Copper-nickel clad
- Typical value range: $3 – $15
