Frequently asked questions
Does 1964 count for dimes, quarters and half dollars?
Yes. Regular U.S. silver dimes and quarters dated 1964, and 1964 Kennedy half dollars, are eligible. Verify earlier coin types before entering them.
Can I include 1965–1970 Kennedy half dollars?
No. Those circulation half dollars contain 40% silver. The half-dollar input here assumes a 90% coin.
Why does a silver dollar use a different ratio?
Morgan and Peace dollars contain about 0.77344 troy ounces of silver. Their silver weight per dollar of face value is higher than that of these dimes, quarters and half dollars.
Does circulation wear affect the estimate?
Yes. The per-coin figures use nominal silver content. Circulated pieces may weigh less.
Does melt value include collector premiums?
No. The estimate covers silver content only. Dates, mint marks and condition can change the price collectors pay.
