Before You Start Counting
Which Coins Go in the Calculator?
Separate your 90% silver from your 40% Kennedy half dollars. The date matters — especially when you're looking at Kennedy halves.
90% Silver
1964 & Earlier
U.S. dimes, quarters and half dollars made for circulation contained 90% silver through 1964.
40% Silver
1965–1970 Kennedy Halves
The 40% section of this calculator is specifically for Kennedy half dollars dated 1965 through 1970.
Check the Date
A Kennedy half dated 1964 is 90% silver and belongs in the 90% section.
Kennedy halves dated 1965–1970 contain 40% silver and belong in the 40% section.
Regular 1971 Kennedy half dollars are not part of the 40% silver series.
1964 Is the Date to Remember
1964 was the final year of 90% silver U.S. dimes, quarters and half dollars issued for circulation. Beginning in 1965, dimes and quarters changed composition, while Kennedy half dollars continued with a 40% silver composition through 1970.

Face Value vs. Silver Weight
$1 Face Does Not Equal 1 Troy Ounce of Silver
Face value is simply the monetary denomination printed on the coins. It is not a measurement of the amount of silver inside them.
10 silver dimes
= $1.00 Face
4 silver quarters
= $1.00 Face
2 silver half dollars
= $1.00 Face
$1 Face in 90% Silver ≈ 0.715 Troy Oz
For circulated 90% U.S. silver coinage, approximately
0.715 troy ounce of silver per $1 face value is a
commonly used dealer convention. Actual silver content
can vary slightly with wear.
Talking Silver
Why Face Value Matters When You're Selling
Dealers commonly describe quantities of circulated
U.S. 90% silver by face value. It provides a simple
way to describe a mixed group of dimes, quarters and
half dollars without treating every coin as though it
were a one-ounce piece of silver.
If you know your face value before you call or visit,
you can give our coin department a much clearer idea
of the quantity of silver you have.
500 Silver Dimes
$50 Face
120 Silver Quarters
$30 Face
40 Silver Half Dollars
$20 Face
Total 90% Silver
$100 Face
Approximately 71.5 troy oz of silver using the
circulated 90% convention.
Large or Inherited Collection?
Before You Count Everything…
You don't need to identify every date, mintmark or variety before bringing a collection to Gulf Coast Coin & Jewelry.
Keep coins in their existing holders, albums, rolls or containers when possible. Some coins that appear to be ordinary silver may have collector value beyond their metal content.
Don't Clean Your Coins
Cleaning or polishing can damage a coin's original surfaces and potentially reduce its numismatic value. Bring the coins in as you found them.

Frequently Asked Questions
Silver Coin Calculator FAQ
A few common questions before you count, sort or bring your silver coins to Gulf Coast.
For the calculator, yes, because each denomination has a different face value. You do not need to extensively organize or sort a collection before bringing it to Gulf Coast Coin & Jewelry.
No. A 1964 Kennedy half dollar is 90% silver. Enter it with your 90% half dollars. The 40% silver Kennedy composition covers 1965 through 1970.
Do not enter a regular 1971 Kennedy half dollar into this 40% calculator. The 40% silver Kennedy composition covered 1965–1970.
No. Morgan and Peace silver dollars have a different silver content and may also carry significant collector value. They should be evaluated separately rather than entered into this face-value calculator.
Do not enter them here. Certain Jefferson nickels issued from 1942 through 1945 contain 35% silver and have a different silver content from the 90% and 40% coins covered by this calculator.
No. Cleaning can alter a coin's surfaces and may reduce collector value. Bring your coins in as they are.
You do not need to manually count an extremely large collection before contacting us. Call Gulf Coast Coin & Jewelry or bring the collection in so our coin department can help determine the best way to review it.
No. The calculator determines face value and provides an approximate silver-content figure. Purchase quotes depend on the current market and the actual coins being reviewed.
Silver-content calculations are estimates for educational purposes.
The 0.715 troy oz per $1 face figure is a commonly used convention
for circulated 90% U.S. silver coinage. Actual silver content may
vary with wear. Dates, mintmarks, varieties and condition can give
individual coins collector value beyond their silver content.
