The story behind the coin
In 1996 the Olympic Games came to Atlanta, and they came with a flood of coins.
To mark the 100th anniversary of the modern Olympics, Congress authorized not one commemorative coin but sixteen — a sprawling two-year program of half dollars, silver dollars, and gold five-dollar pieces, each honoring a different sport or theme. It was the largest single commemorative coin program the United States had ever attempted. The Swimming half dollar was one small entry near the end of it.
By the time it went on sale, collectors were worn out. Buying all sixteen coins, in both proof and uncirculated, in silver and gold, ran into thousands of dollars. Most people simply stopped keeping up. The 1996 issues sold far worse than the 1995 ones — and the Swimming half, a humble fifty-cent piece arriving in the program's exhausted final stretch, sold worst of all.
The Mint struck only 49,533 uncirculated examples. That is the lowest mintage of any U.S. commemorative half dollar struck in the modern era — the run of commemoratives that began in 1982. A coin authorized for three million ended up scarcer than almost anyone intended. The neglect at the sales counter is precisely what makes it prized at the auction block today.
