Since you don't see to many coins from the 1700's or 1800's floating around as change, lets stick to 1932 and up. From 1932-1964 as well as S minted marked silver proofs starting in 1992 the quarters were made of .900 silver and .100 copper. Actual pure silver was .18084 oz. In 1976 they made some silver clad quarters, the out side layers were .800 silver and .200 copper, bonded to an inner layer of .209 silver and .791 copper. The quarters from 1965-2007 except for the silver proofs mentioned before here, are made of .750 copper .250 nickel outer layers bonded to an inner core of pure copper. So there are actually 3 types, silver, silver clad and clad. Hope this helps.

Washington quarters from 1932 - 1964 were made of 90% silver. Quarters from 1965 to the present are made from nickel (the shiny silver looking metal) and copper (the orange like color in the middle). Washington quarters that are made from silver are obviously worth more than those made from 1965 and on as the price of silver has been going up lately.

one dollar, 50 cents & 25 cents contained in the ration a million:2:4 ability a million x one dollar + 2 x 50 cents + 4 x 25 cents = 3 money If the completed volume is seventy 5 money, seventy 5/3 = 25. Multiply with 25 to all parts. 25 x one dollar + 50 x 50 cents + one hundred x 25 cents = seventy 5 money So your answer will be (b) 50

US Quarters Metal Composition:
Bust Quarters(pre-1839) : Alloy of 89.2% silver and 10.8% copper.
Seated Liberty to Washington 1964 Quarter, and silver version State Quarters : Alloy of 90% silver and 10% copper.
Washington Bicentennial 1976 silver version Quarter : Silver-clad, Blank of 20.9% silver and 79.1% copper alloy clad with alloy of 80% silver and 20% copper. (aggregate of 40% pure silver)
Washington post-1964 and regular State Quarters : 100% copper blank clad with 75% copper and 25% nickel alloy.
The layering that you see on the edge of post-1964 quarters is the result of cladding.
