In this article, let’s explore nine extremely rare and expensive half dollar coins that can still occasionally be found in circulation. If you’re lucky, a simple coin can change your life.
1974 Aluminum Half Dollar
In 1974, the U.S. Mint conducted a unique experiment. To reduce production costs, they minted half dollar coins from aluminum instead of the traditional copper-nickel. Most of the coins were later destroyed, but a few specimens survived and found their way into private hands.
In 2023, one such coin sold for $12,000 (approximately ₹10 lakh).
Its distinctive feature is its light weight and rarity. If you’ve ever found a half dollar coin unusually light, this might be it!
