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.
Since 1965, US quarters have been made of 91.67% copper and 8.33% nickel. Dimes and half dollars also have the same composition.
