The composition of a 40% silver US coin is the outer layers are .800 silver & .200 copper bonded to the inner core of .209 silver and .791 copper.
You need to be more specific. Clad just means the coin is layered.
Yes, it can also contain silver. Experts can tell by holding the coin & observing its edge & by its weight. Clad coins are usually lighter
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".
The 1973 proof Eisenhower dollars were struck in 40% silver clad and copper-nickel clad. Average retail value of the CN coin is $7.00, the 40% is $14.00.
It depends on if it's a 90% silver coin, a 40% silver coin or a clad coin. Also why the date is missing. Take it to a coin dealer it MAY BE worth up to $20.00.
The color is different. The silver is more reflective. If you cover the coin with a Kleenex you can barely see the CN coin but the silver one shows through.
It depends on the type. There were two types: silver-clad and a copper-nickel-clad. Silver-clad contains 0.14792 ounces of pure silver. All have an S mint mark. Copper-nickel-clad does not contain any silver. They can have a D, S, or no mint mark.
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.

All the bicentennial 40% silver clad coins were struck at the San Francisco Mint and have the "S" mintmark. If the coin is missing one of the designers initials, post new question.
