What is the value of a US sterling silver quarter?
US quarters were never made of sterling silver. Sterling silver is 92.5% silver and 7.5% copper; it's most commonly used in silverware, jewelry, and other decorative items but is too soft for use in coins. Up till 1964 quarters were struck in "coin silver" which is 10% copper. That extra 2.5% was enough to make the alloy hard enough to stand up to daily wear. At a minimum a common-date silver quarter is worth about 1/7 the price of an ounce of silver if melted. Older ones can be worth considerably more to a collector but you need to know the date, mint mark, and condition to determine a value.
How much is a 1964 pure silver dime worth?
The U.S. never made 100% silver coins for circulation. The metal would be too soft for daily use. All silver coins had at least 10% copper in them. Dimes dated 1964 and earlier contain about 0.07 ounces of silver. The price of silver changes so you'd need to search on terms such as SPOT PRICE SILVER to get the most current value, then multiply the price per ounce by 0.07. For example, at $14/oz a 1964 dime contains about $1 worth of silver.
