A dollar coin may look like ordinary change, but some are worth far more than the $1 printed on them. Some U.S. dollar coins have sold for millions because of their age, rarity, condition, and unusual features.

Silver dollars from the country’s early years are especially popular with collectors. Some were produced in very small numbers, while others stand out because of tiny design differences or unusual minting details.

Several coins on this list date back to the U.S. Mint’s earliest days. Here are 10 valuable examples featured by USA Coin Book, along with their estimated values.

1794 Flowing Hair Silver Dollar (Silver Plug)

Estimated value: $12.9 million

The 1794 Flowing Hair dollar is one of the most famous coins in American history, but this version has an extra detail that makes it even rarer: a small silver plug. Mint workers used these plugs to adjust a coin’s weight, and only a limited number of examples with this feature are known.

Its place among the first U.S. silver dollars, combined with its age and scarcity, accounts for its remarkable estimated value.

1794 Flowing Hair Silver Dollar

Estimated value: $6.2 million

The 1794 Flowing Hair silver dollar was struck during the first year the U.S. Mint produced silver dollars. Its design features Liberty with flowing hair on the front and an eagle on the reverse.

The original mintage was limited, and relatively few examples have survived in collectible condition. For coin collectors, this dollar represents an important piece of early American history.

1870-S Seated Liberty Silver Dollar

Estimated value: $2.1 million

The 1870-S Seated Liberty dollar is a rare San Francisco Mint find. It carries the Seated Liberty design, which appeared on several U.S. silver coins during the 19th century.

Very few examples are known today, making this one of the hardest Seated Liberty dollars for collectors to acquire. Its scarcity is a major reason for its high estimated value.

1795 Flowing Hair Silver Dollar (Silver Plug)

Estimated value: $1.8 million

This 1795 Flowing Hair dollar has a small silver plug added to adjust its weight. The feature shows how early U.S. Mint workers handled the challenges of producing coins to the required standards.

Flowing Hair dollars from the 1790s are already scarce, and the silver plug makes this particular variety even harder to find. Collectors interested in early American currency place a high value on examples like this.

1796 Draped Bust Silver Dollar (Small Date, Small Letters)

Estimated value: $1.4 million

The 1796 Draped Bust dollar comes in several varieties, and this one is identified by its Small Date and Small Letters. The differences are subtle, but they matter to collectors who study early U.S. coins.

Its age, limited availability, and distinct lettering and date make this variety especially desirable. A coin that looks similar at first glance may have a very different value.

1803 Draped Bust Silver Dollar (Proof Restrike)

Estimated value: $1.2 million

This 1803 Draped Bust dollar is a proof restrike, meaning it was made later using dies from an earlier period. Proof coins were struck with extra care, giving them sharper details and a more polished finish.

Only a small number of these restrikes are known, which adds to their appeal among collectors. Their unusual production history also sets them apart from regular circulation dollars.

1802 Draped Bust Silver Dollar (Proof Restrike)

Estimated value: $1.2 million

The 1802 Draped Bust proof restrike is another rare example of early U.S. coinage. Its value depends on the limited number of known pieces and collectors’ interest in early proof coins.

Finding one is difficult, especially for collectors looking to complete a set of early American silver dollars. Its scarcity helps explain the high estimated price.

1801 Draped Bust Silver Dollar (Proof Restrike)

Estimated value: $1.2 million

The 1801 Draped Bust proof restrike is another hard-to-find early 19th-century dollar. It features the Draped Bust design, with Liberty on the front and an eagle on the back.

Its rare proof status, age, and small number of surviving examples make it a prized coin. Collectors who focus on early U.S. silver dollars often pay close attention to pieces like this.

1795 Draped Bust Silver Dollar (Off-Centered Bust)

Estimated value: $1.2 million

This 1795 Draped Bust dollar is known for its off-center portrait, which sets it apart from standard examples. Minting errors can make coins more desirable, especially on rare pieces from the country’s early years.

The unusual portrait placement is a major part of this coin’s appeal. Its age and limited availability make it even more interesting to collectors.

1795 Flowing Hair Silver Dollar (Two Leaves Variety)

Estimated value: $1.09 million

The Two Leaves variety of the 1795 Flowing Hair dollar gets its name from a small detail on the reverse. Beneath the eagle, the design features two leaves, setting it apart from other varieties.

That small feature can make a major difference for collectors seeking specific versions of early silver dollars. Its age, historic design, and rarity help account for its estimated value.
