For every coin collector, the hope of stumbling upon a rare and valuable piece is thrilling. But few stories match the excitement of discovering a Kennedy Half Dollar tucked away in an old drawer—only to realize it’s a rare off-center strike worth an incredible $720,000.
This stunning find highlights how minting mistakes can carry significant worth, blending history, rarity, and the thrill of chance.
What Is an Off‑Center Strike—and Why It Matters
An off-center strike occurs when a coin is misaligned during the minting process, causing its design to be imprinted off to one side. Depending on the extent of the misalignment, these coins can be worth much more than face value.
While minor off-center coins might fetch modest premiums, more dramatic examples—like this Kennedy Half Dollar—can reach six-figure values. Even recent examples, such as the 2020 Kennedy half dollars with additional die errors, have been known to sell for over $130.
