Every family attic hides its secrets. Some are old letters, others are yellowed photos, and sometimes it is nothing more than dust.

But one family’s unexpected discovery, tucked away inside a long-overlooked box that had been sitting quietly for years without much attention, turned out to be something far rarer and more extraordinary than anyone could have reasonably anticipated.

Instead of trinkets or keepsakes, they stumbled upon a silver coin that experts call the “King of American Coins,” a find now expected to sell for millions.


The coin was part of a collection belonging to James A. Stack Sr., a well-known New Yorker with a passion for rare currency. His heirs thought most of his holdings had been auctioned off decades ago, but a forgotten group of coins recently surfaced.

Inside that group was a silver dollar dated 1804, a year that collectors instantly recognize. Only 15 of these coins were known to exist—until now, when this discovery pushed the number to 16.

What makes the coin so fascinating is that it was never meant for everyday use. In the 1830s, President Andrew Jackson ordered the Mint to produce gift sets for visiting rulers.

Because no silver dollars had been struck since 1804, new ones were made with that year stamped on them. These diplomatic tokens went to leaders like the King of Siam and the Sultan of Muscat, creating a rarity that has captivated collectors ever since.


Later, a few more were secretly produced at the Mint in the mid-19th century to satisfy wealthy buyers.

Historians believe the Stack family’s newly uncovered example comes from that later run, not the first diplomatic batch.

That detail does not diminish its value, however. With only 16 known today, even the “second wave” coins are among the most coveted objects in American numismatics.

The record price for one of these coins was set in 2021, when an 1804 silver dollar sold for $7.68 million.

With the market still strong, experts believe this one could easily approach or surpass $5 million when it is offered at auction this December by Stack’s Bowers Galleries.

Before the sale, the coin will go on public display so collectors and the curious alike can catch a glimpse of it.

Of course, stories like this always spark a question: what about the change rattling around in your own house?

Most jars of coins will never contain a once-in-a-lifetime rarity, but surprising finds do happen. A Lincoln penny sold this year for over $200, a buffalo nickel topped $1,000, and even a 1971 Eisenhower dollar shocked the hobby by bringing in $264,000.

Ordinary coins can become extraordinary if the right quirks are present. That is part of the magic of collecting. Coins are more than metal—they are fragments of history, each carrying a story from the time it was struck.

The 1804 silver dollar embodies that idea perfectly, blending diplomacy, mystery, and rarity in a way few other objects can.

And now, thanks to one family’s forgotten attic box, another chapter is being added to its remarkable tale.
