What does a dollar coin look like? If you’ve ever wondered what a dollar coin looks like, you’re not alone. Dollar coins capture the imagination of coin collectors and curious minds alike with their unique designs and shiny appearance. In this comprehensive guide, we’ll walk you through everything you need to know about the look and design of various US dollar coins over the years.
If you’re short on time, here’s the quick answer: Standard circulation dollar coins in the United States typically feature the busts of prominent American statesmen and women on the front (obverse) side with an eagle design on the back (reverse) side.
They have a golden color, ridged edges, and range between 26.5 and 27.5mm in diameter.
Key Physical Attributes of Dollar Coins
Diameter and Thickness
The diameter of a dollar coin in the United States is 26.5 mm (1.043 inches), making it the largest circulating coin denomination. The thickness is 2.00 mm (0.079 inches). This size and thickness make the dollar coin much more substantial and heavier than other smaller denomination coins like dimes, nickels, and pennies.
The heft gives the coin a solid feel.
Weight
With the diameter and thickness specifications, a dollar coin weighs 8.10 grams. This gives the coin noticeable weight, especially compared to paper dollar bills that weigh about 1 gram. Some key differences in the coin weights across other denominations are:
- Penny: 2.5 grams
- Nickel: 5 grams
- Dime: 2.268 grams
- Quarter: 5.67 grams
The increased weight makes dollar coins more durable for circulation than paper money. According to the Federal Reserve, the average lifespan of a $1 coin is 30 years, while a $1 bill lasts just 5.9 years.
Color and Composition
Modern circulating dollar coins in the U.S. are golden in color due to their composition. They are made of copper alloy, with a composition of 88.5% copper, 6% zinc, 3.5% manganese, and 2% nickel. This golden hue contrasts with dimes and quarters which have a silver appearance from their nickel alloy composition.
Over the years, there have been different variations in the dollar coin color and metals:
- Susan B. Anthony Dollars (1979–1981 + 1999): Silver-gray color from a copper-nickel-clad composition
- Sacagawea Dollars (2000–present): Golden color from a copper alloy
- Presidential Dollars (2007–2016): Golden color from the same copper alloy as Sacagawea dollars
Edges
The edge of a circulating U.S. dollar coin has an intermittent dentilated border (repeating line patterns along the rim). This reeded or grooved pattern helps distinguish the denomination during coin handling without visual reference. The edges also deter filing or clipping to steal slivers of metal.
In contrast, the edge of a quarter has an unbroken dentilated border. Dollar coins also have wider spacing between the edge lines compared to smaller coins. Additionally, some special commemorative dollar coin editions may have decorative incused inscriptions or designs along the rims.
Obverse (Front) Designs
Susan B. Anthony Dollar
The obverse of the Susan B. Anthony dollar coin features a profile portrait of Susan B. Anthony, a prominent women’s rights activist in the 19th century. Her portrait is depicted facing left, with the inscriptions “LIBERTY” above and “IN GOD WE TRUST” below.
13 stars representing the 13 original US colonies surround her portrait. This design by Frank Gasparro was selected through a public competition.
Sacagawea Dollar
The obverse of the Sacagawea dollar depicts Sacagawea, the Lemhi Shoshone woman who assisted the Lewis and Clark expedition as an interpreter and guide in their exploration west of the Mississippi River. Her portrait faces right, wearing a Native American headdress.
The inscriptions are “LIBERTY” above and “IN GOD WE TRUST” below in a curved line. To the left of her portrait is the mint mark of the facility where the coin was manufactured.
Presidential Dollar Coins
The obverse design of the Presidential dollar coins features portraits of former U.S. Presidents in order of service, starting with George Washington. Their portraits facing left, with the statutory inscriptions “IN GOD WE TRUST”, the year of minting, and the mint mark.
To date, Presidential dollar coins have been released for Presidents Washington to Arthur, with 4 presidents honored each year in the series. This program was signed into law in 2005 but production ceased in 2016 due to oversupply and insufficient demand.
Reverse (Back) Designs and Inscriptions
Susan B. Anthony and Sacagawea Dollars
The back of the Susan B. Anthony dollar coin depicts an eagle in flight, symbolizing liberty. The coin was minted from 1979-1981 and 1999. Later versions included 13 stars, representing the original 13 colonies, and the inscriptions “UNITED STATES OF AMERICA” and “$1.”
The Sacagawea dollar coin reverse features an eagle in flight, carrying peace pipes and an olive branch. The central devices depict Sacagawea and her infant son, Jean Baptiste, with the inscription “IN GOD WE TRUST.” The date, mint mark, and the inscriptions “UNITED STATES OF AMERICA” and “$1” also appear on the reverse.
Presidential Dollar Coins
The reversing design of the Presidential $1 Coin Program depicts the Statue of Liberty. The portrait symbols of the presidents’ lives appear in the coin’s field and edge. The inscriptions “UNITED STATES OF AMERICA,” “$1,” the year of minting or issuance, and the mint mark also appear on the reverse.
For example, John Adams’ coin includes a quill pen and inkwell, representing his role as a patriot leader and author. Inscriptions include “JOHN ADAMS” and “2nd PRESIDENT” with his presidential term.
The program ran from 2007-2016, honoring 4 presidents per year in the order served. The U.S. Mint made over 1.4 billion presidential dollar coins before ending the program due to oversupply and lack of demand from the public.
Special Design Variations
Proof Versions
Proof versions of dollar coins feature a special minting process that results in sharper details and a more mirror-like surface. According to the U.S. Mint, proof coins receive multiple strikes from polished dies to create the crispest images and fields possible.
After minting, proof dollar coins go through specialized handling to preserve their condition.
These premium collectible versions truly showcase the artwork on dollar coins. For instance, the 2023 Native American dollar’s reverse-proof design has a stunning mirrored finish that makes Sacagawea and her baby shine.
Proof coins cost more than normal circulation strikes but make an excellent addition to any collection.
Uncirculated Versions
Similar to proof versions, uncirculated dollar coins also go through special handling after minting. However, uncirculated versions feature more of a matte finish rather than a high mirror polish. According to the U.S. Mint, the dies used to strike uncirculated coins do receive polishing but not to the level of proof dies.
Nonetheless, uncirculated dollar coins stand out from normal circulation strikes with their pristine, mark-free surfaces. These coins are another great way for collectors to own flawless examples of dollar coin designs.
Uncirculated versions are available for certain Native American and Presidential dollar coins.
