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.
Nickel is magnetic.
By the color, obviously. NIckel plated flutes are slightly golden and well, silver plated, they have silver color.
One way to tell the difference between silver and silverplate is to look for a hallmark or stamp that indicates the metal content. Silver will typically be marked with a number such as "925" or "Sterling," indicating that it is real silver, while silverplate will often be marked with terms like "EPNS" (Electro Plated Nickel Silver) or "A1." Additionally, silverplate will generally have a layer of another metal, such as nickel or copper, underneath the thin silver coating.
You can differentiate between a silver nickel and a regular nickel by checking the date on the coin. If the date is 1942-1945, it could be a silver nickel as those were made with silver during World War II. Regular nickels are made primarily of copper and nickel. You can also use a magnet to check - silver nickels are not magnetic, while regular nickels are.
Brass is a yellow-colored alloy made from copper and zinc, while nickel is a silver-colored metal with a slight blue tint. Brass tends to have a warmer tone and is less shiny than nickel. You can differentiate between the two by comparing their color, shine, and possibly using a magnet (nickel is magnetic, while brass is not).
Copper nickel coins usually have a lighter color and weigh less than silver coins. You can also conduct a magnet test - copper nickel coins are magnetic while silver coins are not. Another method is to look at the edge of the coin where a copper nickel coin will have a distinct reddish tinge, unlike the silver coin.
They are smart enough to recognize the difference between objects of different sizes. They can be trained to learn the names of the objects.
Nickels minted between 1942-1945 during World War II were made with a composition of 35% silver because of nickel shortages. You can check the edge of the coin for a large "P," "D," or "S" mintmark above Monticello to distinguish these silver nickels from regular ones.
German silver is an alloy of copper, zinc, and nickel, while Monel is a nickel-copper alloy. Monel typically has a higher nickel content compared to German silver, giving it a more silver-like appearance. Additionally, Monel is more resistant to corrosion and tarnish compared to German silver.
Replica coins are required to have the word "COPY" stamped on them somewhere.
A genuine silver coin produced by the Royal Mint will be in protective packaging indicating what the coin is made from. It should also include a certificate of authenticity.
