1964 Proof Set: Last Year Of Circulating 90% Silver Coins & First Year Of Kennedy Half Dollars

by Joshua McMorrow-Hernandez
The 1964 proof set is the first to contain the Kennedy half dollar.

If you’re into hunting for silver, the 1964 proof set is pretty much the holy grail of affordable sets.

This was the absolute end of an era for the U.S. Mint — making it a must-have for anyone trying to stack some historical premium metal without breaking the bank.

Here’s why this specific set is such a big deal in the coin community…

Why the 1964 Set is Total Legend Status

  • The Last of the Real Silver: This set represents the grand finale for regularly circulating pocket change struck in 90% fine silver. After 1964, the Mint went on a silver strike hiatus for proof sets until they finally brought back dedicated silver proof sets in the 1990s.
  • The Big Denomination Shift: If you look at dimes, quarters, and half dollars from ’64, they are loaded with silver. But starting in 1965, the government switched over to a cheaper copper-nickel clad composition we carry around today.
  • The 40% Half Dollar Markdown: Even the half dollar took a massive hit. In 1965, its silver content was heavily diluted down to a mere 40% composition.
  • Hello, JFK! Aside from being the last year for 90% silver, 1964 marked the very first appearance of the legendary Kennedy half dollar in a proof set. It’s the ultimate double-whammy of numismatic history.

What’s It Gonna Cost You?

The absolute best part about the 1964 proof set is that it won’t clear out your wallet. Despite all that silver and historical hype, it remains one of the single most popular and dirt-cheap silver sets on the market.

Retail Value: You can buy a complete, authentic 1964 proof set for anywhere between $75 and $100 from almost any local coin shop or online dealer.

Have you ever cracked open a 1964 proof set to check the fields? Or do you prefer keeping them tucked away in their original government packaging?
