Cupronickel sets typically have a reddish tint due to the copper content, while silver sets have a brighter, white-silver color. You can also use a magnet to distinguish between them - silver is non-magnetic, while cupronickel is slightly magnetic. Finally, you can perform a acid test or take it to a professional to determine the metal composition.
Nickel silver is an alloy of nickel, copper, and zinc, while sterling silver is an alloy of silver and copper. You can tell the difference between the two by looking for a marking such as "925," which indicates sterling silver's higher silver content compared to nickel silver. Sterling silver will also have a brighter appearance and may tarnish less than nickel silver.
Circulation strikes of silver-clad halves ended in 1969. Additional clad halves were minted for collectors in 1970, 1975, and 1976 but were only available in special sets:1970-D: sold in Mint Sets1970-S: sold in Proof sets1975 and 1976: sold in 3-coin Bicentennial sets including a quarter and dollar as well. All carry an "S" mint mark and the dual date 1776-1976 regardless of the year of mintingAny silver-clad Bicentennial coins that may have accidentally ended up in circulation (e.g. if a set was broken up and spent) can be identified by looking at their edge. Cupronickel versions show the familiar pure copper core, while the copper/silver core of silver-clad coins appears as a dirty gray color.
By its date: 1964 halves were made from an alloy of 90% silver and 10% copper. 1965-69 coins are technically clad coins, but were made with outer layers of 80% silver and an inner core of 20% silver that resulted in an overall composition of 40% silver, 60% copper. 1970 halves were only released in collectors' sets 1971 and later halves made for circulation and most proof sets are copper-nickel clad. The ones sold in special "Presitige" sets are 90% silver but they do not circulate.
If it's a US quarter minted in 1965 or later, it's not silver (there are silver coins minted in "proof sets", but these came in a special labeled display case; you're not going to find one in pocket change). US quarters minted in 1964 or before were partly (about 90%, I think) silver.
If its date is 1964 or earlier, it's made of an alloy of 90% silver and 10% copper. All circulating dimes dated 1965 and later are made of copper-nickel, with no silver at all. Starting in 1992, special "Prestige Proof" coin sets have been issued for sale to collectors; the dimes in these sets are again made of 90% silver but these coins don't circulate.
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.
Very simply: All Buffalo nickels, regardless of date, are made of a cupronickel alloy. None of them ever contained silver.
If it is a "Silver" coin, it will say so on the case it came in.
1964 is the last date for silver quarters. To be annoyingly technical, 1964-dated silver quarters were actually struck for a while in 1965 during the transition to cupronickel coinage, but there's no way to tell them apart from coins made during calendar 1964.

You can tell the difference between diecast and other model train sets in stores by reading the box carefully. Normally, diecast train sets are built to scale.

They are now made of copper and nickel. Silver quarters have a melt value of around $6.

There are several ways to tell the difference between nickel and silver. Silver is much softer than nickel. However, nickel will shine with a cloth while silver needs special cleaners. Finally, silver is more reflective than nickel.
