25¢.
Please check your pocket change beforehand. You'll find over 40 years worth of common, ordinary clad coinage. With only a few very obvious exceptions, they're all worth face value.
It is unlikely that you have a clad 1964 quarter, all quarters dated 1964 should be 90% silver, not the copper-nickel clad of 1965-present. Look on the rim of your coin, if it is a solid color (usually solid white but silver tones easily to different colors) it is silver, if it has a line of copper through it it is clad (compare it with a quarter from your pocket change). If it is clad, it is an error and worth quite a bit of money. If it is silver it is worth about $6 for the silver content.
A 1975 quarter contains no silver and is not the slightest bit rare. It's worth exactly 25 cents. NOTE: No U.S. quarters are dated 1975. The coins struck in 1975 all have the dual date 1776-1976.
No 1964 U.S. quarters were copper clad. They were all 90% silver (it was the last year for silver quarters).
Like all circulating clad quarters made since 1965, it's only worth a quarter.Also the coin is called a Washington quarter. The last circulating quarters with a picture of Miss Liberty were made way back in 1930.
A 1981 U.S. quarter is worth 25 cents. You should have no trouble finding this date and others back to 1965 in common circulation. All are made of copper-nickel clad metal, and none are worth anything special.
Not in a US quarter, although a 1965 Canadian quarter is 80% silver.
No, clad is used in the coin collecting community talking about the Copper and Nickel "sandwich" current, non-silver, coins have. So a clad quarter by definition would not have any silver because a clad quarter is a quarter with no silver. However, quarters were made of silver before 1965 so any quarter dated 1964 and earlier contains 90% silver, but those coins would not be considered "clad".
These regularly sell in the $300 to $400 range.
If they're from circulation, they're cupronickel rather than silver and are only worth face value. If they're in mint sets, they'd be worth a bit more if made from the same clad stock as circulation coins. Eisenhower dollars were also struck in silver-clad composition and are worth to retail in that case.
The coin was struck over a 1941 Canadian quarter. It takes a keen eye to see the print of the Canadian coin on the American coin. A 1941 Canadian quarter was made of silver and the American quart was a clad coin (copper line in the reeded edge). So, it would seem finding silver 1970-D (no copper line) would be easier to see than the faint imprint of the Canadian quarter.
It depends on the quarter. From 1932-1964 silver quarters had the familiar Washington eagle design on the back, just like clad quarters up until the state quarter series. The Standing Liberty quarters depict an Eagle in flight, the barber quarter has a heraldic eagle on the reverse and earlier coins usually have something stating that it is a quarter of a dollar.
Very few clad quarters are worth any premium. If it's uncirculated AND in its original packaging, 50 cents. Otherwise face value only, despite its age and condition.
