You can darken silver coins by placing them in the presence of hydrogen sulfate, which you can obtain in great abundance from boiled eggs (it is the fart smell that comes from these delicious but wretched smelling things), or from rotten eggs if you don't mind throwing up while you're doing it.
The big problem here, however, is to find a "silver" coin, since no "pocket change" coin in North America has been made of silver in the past 30 years. You will have to find a very old dime or quarter, or you will need to purchase from the mint a current silver coin at 4 to 20 times its actual face value.
Because silver is far too expensive. Coins used to contain silver until about 1920 in the UK, 1965 in the U.S., and 1968 in Canada. Since then they are made from a mixture of copper and nickel, so they really aren't called "silver" coins anymore.
Silver coins are typically shinier and have a higher metallic sound when dropped compared to pewter coins. Silver coins are also heavier than pewter coins due to their higher density. Additionally, silver coins may have distinct markings or engravings indicating their silver content.
This is a chemical reaction where silver metal reacts with sulfur in the air to form silver sulfide. The silver sulfide appears as a darker tarnish on the surface of the silver metal due to the formation of the compound.
Contact between silver coins and sulfur can cause tarnishing of the silver due to a chemical reaction between the two materials. Sulfur reacts with the silver to form silver sulfide, which appears as a black tarnish on the surface of the coins. It is best to keep silver coins stored in a cool, dry place away from sulfur-containing materials to prevent tarnishing.
You can check if your coins are real silver by looking for specific markings such as "STERLING," "SILVER," or "AG" (the chemical symbol for silver). You can also perform tests like a magnet test (silver is not magnetic) or using a silver testing kit to determine the authenticity of the coins. Additionally, seeking a professional appraisal or consulting a reputable coin dealer can help authenticate your silver coins.
Germany had silver 5 DM circulation coins until 1975.
The Romans used bronze, silver and gold to make their coins.

The value of silver rose so the US had to use other metals to make coins. If our coins were still made of silver dimes would be worth $2 and quarters would be worth $5.
Yes, but none of the coins were made for general circulation. Silver Proof quarters sets and Silver Proof 10-piece sets were sold by the Mint, also the American Silver Eagle bullion coins were minted in 2006.
i don't know maybe they hate silver. lol

Depends on what type of coins we are looking at.Coins have been minted with weights ranging anywhere from 1/20th (or less!) of an ounce of silver to 5 ounces + of silver.
Whether you should purchase silver coins or silver bars depends on why you are purchasing silver. If you are a coin collector or want silver items that make a pleasing display, coins are probably preferable. If you are purchasing silver as a hedge against inflation, you may prefer bars, but may want to consider the security of where you will keep them.
The silver used to make predecimal British coins could have been mined anywhere in the then British Empire. A lot of silver was also acquired from raids on Spanish ships.
It would depend on who you mean by "they", but up until the mid 20th century, silver had been used to make coins for over two thousand years.
