BUT - please don't try to clean them because cleaning will damage the metal and reduce their value.

What are the 2000 silver quarters made of?

Modern silver quarters are only made for sale in special "Prestige" proof sets sold to collectors. They're made of the same 90% silver / 10% copper alloy that was used for circulating quarters before 1965. Circulating quarters dated 1965 and later are made of nickel and copper, and do not contain any silver.

How can you tell if a dime or quarters are silver?

You can tell if a dime or quarter is silver by checking the year minted. Dimes minted before 1965 and quarters minted before 1964 are made of 90% silver. You can also conduct a magnet test - if the coin is attracted to a magnet, it is not silver.


Can you melt silver quarters?

Yes, it is possible to melt silver quarters. Silver quarters are typically made of 90% silver and 10% copper, so melting them down can separate the silver from the other metals. However, keep in mind that altering currency in this way may be illegal in some jurisdictions.


Are silver quarters solid silver or are they silver plated?

US Silver quarters (produced as regularly circulated coinage through 1964, and as part of silver proof sets since the early 1990's) are an alloy of 90% silver and 10% copper. They are not plated, but rather a consistent 90% silver alloy throughout the coin. Quarters dated 1965 and later don't contain any silver. They're made of a "sandwich" consisting of outer layers of 25% copper and 75% nickel bonded to an inner core of pure copper.
