The current clad version is two layers of copper/nickel (75% Copper, 25% Nickel) on a core of pure copper giving a total composition of 8.33% Ni with the remainder Cu.
Not in mass, weight, luster, appearance, physical dimensions, or composition, but they do in purchasing power and common value.
A 1997 quarter, like all U.S. quarters minted since 1965, weighs 5.67 grams. This weight applies to both the clad quarters made of a copper-nickel composition and the earlier silver quarters. The dimensions and weight have remained consistent for these coins over the years.
the edges will be all silver instead of the a normal quarter that is copper with nickel platingYes, but ...The most general way is by date. All quarters dated 1964 and earlier are made of 90% silver alloy, and all circulating quarters dated 1965 and later are made of copper-nickel clad composition (NOT nickel plating; there's a major difference). The US has struck quarters in silver since 1965, but all of these carry an S mint mark and were made for inclusion in special collectors' sets. Specifically, some 1776-1976 Bicentennial quarters were made of a 40% silver clad composition, and since 1992 90% silver composition has been used in special "Prestige" proof coins.

25 cents. 1965 was the first year of issue with the copper-nickel composition that current quarters have. In 1965 many, many, many quarters were minted and so it isn't a rare year. If you look hard enough, you can find many 1965 quarters in pocket change.
