A Morgan or Peace silver dollar contains 0.7734 troy oz of silver. These classic U.S. silver dollars were struck from an alloy containing 90% silver and 10% copper, with a standard weight of 26.73 grams. The U.S. Mint documents the 26.73-gram, .900-fine standard used for the Morgan dollar.
Not every U.S. dollar coin contains that amount of silver. Regular Eisenhower dollars were copper-nickel clad, although special collector versions were made with a 40% silver composition. Susan B. Anthony dollars contain no silver.
So, how much silver is in a silver dollar depends on which dollar you have. Identify the coin before calculating its metal value.

How Much Silver Is in Each U.S. Silver Dollar?
Morgan and Peace dollars each contain 0.7734 troy oz of silver, while later dollar coins can contain less silver or none at all.
| Dollar Type | Dates | Silver Purity | Silver Content |
|---|---|---|---|
| Morgan Dollar | 1878–1921 | 90% | 0.7734 troy oz |
| Peace Dollar | 1921–1935 | 90% | 0.7734 troy oz |
| Eisenhower Dollar — regular circulation issues | 1971–1978 | 0% | 0 troy oz |
| Eisenhower Dollar — selected collector issues | 1971–1976 | 40% | About 0.316 troy oz |
| Susan B. Anthony Dollar | 1979–1981, 1999 | 0% | 0 troy oz |
This table covers the dollar types people commonly encounter when asking about old U.S. silver dollars. Earlier U.S. silver dollars and later commemorative or bullion coins can have different specifications.
Size alone does not tell you whether a dollar contains silver.
How Much Silver Is in a Morgan Dollar?
The silver content of a Morgan dollar is 0.7734 troy oz at its original standard specifications.
Morgan dollars were struck from 1878 through 1904 and again in 1921. The U.S. Mint states that the standard established for these dollars was:
26.73 grams total weight
90% silver
10% copper
You can calculate the contained silver:
26.73 × 0.90 = 24.057 grams of silver
There are approximately 31.1035 grams in one troy ounce:
24.057 ÷ 31.1035 ≈ 0.7734 troy oz
That is why dealers and collectors use 0.7734 troy oz as the standard original silver content of a Morgan dollar.
Its theoretical silver value is:
0.7734 × current silver spot price
A Morgan dollar may be worth considerably more than that amount because its date, mint mark, variety, condition, and collector demand can add numismatic value.
How Much Silver Is in a Peace Dollar?
The silver content of a Peace dollar is also 0.7734 troy oz.
Peace dollars were struck from 1921 through 1935 and followed the same traditional 90% silver dollar standard.
Their standard specifications give:
26.73 g × 0.90 = 24.057 g silver
Converting that amount to troy ounces:
24.057 ÷ 31.1035 ≈ 0.7734 troy oz
A Morgan dollar and Peace dollar therefore contain the same amount of silver when measured from their original specifications.
Their market prices do not have to be the same.
A scarce Peace dollar can carry a large collector premium, just as a rare Morgan date, mint mark, or variety can trade far above its contained silver value.
How Much Is a Silver Dollar Worth in Silver?
For a Morgan or Peace dollar, multiply the current silver spot price by 0.7734.
The formula is:
0.7734 × silver spot price = theoretical contained silver value
The live calculator above can perform this calculation using the current spot price.
For multiple coins, multiply the number of dollars by 0.7734 first.
For example:
10 Morgan dollars × 0.7734 = 7.734 troy oz silver
20 Morgan dollars × 0.7734 = 15.468 troy oz silver
100 Morgan dollars × 0.7734 = 77.34 troy oz silver
Then multiply the total silver weight by the current spot price.
These figures represent theoretical contained-silver value based on original specifications. They are not guaranteed dealer offers.
A buyer may account for spreads, refining costs, market conditions, and the coin’s numismatic value.
Are Eisenhower Dollars Made of Silver?
Most Eisenhower dollars contain no silver, but special collector issues were produced in a 40% silver composition.
The U.S. Mint introduced the Eisenhower dollar in 1971. Regular coins intended for circulation used copper-nickel cladding rather than silver.
At the same time, the Mint produced special collector versions using a 40% silver alloy. A 1971 Mint announcement explicitly described these collector coins as 40% silver and distinguished them from the cupro-nickel dollars intended for circulation.
The Mint also described the silver-clad strip used for Eisenhower collector coins as having an overall composition of 40% silver and 60% copper.
A 40% silver Eisenhower dollar contains approximately:
0.316 troy oz of silver
That is less than half the silver found in a Morgan or Peace dollar.
Do not assume that a large 1970s dollar is silver based on size or color alone. Identify the specific issue before calculating melt value.
Do Susan B. Anthony Dollars Contain Silver?
No. Susan B. Anthony dollars contain no silver.
The U.S. Mint lists the series as issued from 1979 through 1981 and again in 1999. Its composition is cupro-nickel clad: 8.33% nickel with the balance copper.
Its silver content is therefore:
0 troy oz
Susan B. Anthony dollars cannot be valued using the silver spot price.
Some examples can still be worth more than face value because of condition, varieties, or collector demand, but that value is numismatic rather than silver value.
Why Isn’t a Silver Dollar One Troy Ounce?
A Morgan or Peace dollar contains less than one troy ounce because the entire coin weighs less than a troy ounce and only 90% of that weight is silver.
One troy ounce equals approximately:
31.1035 grams
A Morgan or Peace dollar originally weighs:
26.73 grams
Then only 90% of that weight is silver:
26.73 × 0.90 = 24.057 grams
That converts to:
0.7734 troy oz of silver
The word “dollar” describes the coin’s denomination. It does not mean the coin contains one troy ounce of silver.
This distinction is especially important because modern bullion coins can contain one full troy ounce of silver while also carrying a dollar-denominated face value.
Does Wear Reduce the Silver Content of a Silver Dollar?
Yes. Heavy circulation can remove a small amount of metal from a silver dollar over time.
The standard 0.7734 troy oz figure describes the coin’s original silver content based on its mint specifications.
Friction and handling can gradually wear metal away from high points, rims, and other exposed surfaces. A heavily worn Morgan or Peace dollar can therefore weigh less than its original 26.73 grams.
For basic bullion estimates, 0.7734 troy oz remains the standard figure used for Morgan and Peace dollars.
For large quantities of heavily worn coins being evaluated solely for metal recovery, actual weight may become more relevant.
Do not clean a collectible coin before weighing, selling, or having it appraised. Cleaning can permanently alter the surface and reduce collector value.
Is a Silver Dollar Worth More Than Its Silver?
Many Morgan and Peace dollars sell for more than their theoretical silver value because collectors also value the coin itself.
Factors that affect numismatic value include:
- Date
- Mint mark
- Condition
- Rarity
- Die variety
- Original surfaces
- Collector demand
This distinction matters before you sell.
A common circulated silver dollar may derive much of its value from its silver content plus a market premium. A scarce date or high-grade example can be worth many times its contained-metal value.
The theoretical silver value is therefore a useful reference point, not a complete appraisal.
Before selling an old silver dollar for its metal content, identify its date, mint mark, and variety.
