You don't. You don't EVER clean a gold coin and you don't clean a silver coin.
Cleaning ruins the value of coins! If it has any collector value at all it will be demolished by a cleaning. Cleaning can take a $100 coin into a $10 coin. It will never, ever improve the value of the coin unless you literally dug it out of the ground.
Do not clean coins.
Coins are typically made of a combination of metals, such as copper, nickel, zinc, and sometimes other materials like silver or gold, depending on the denomination and country of origin. Some older coins also contain precious metals like platinum or palladium.
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.
Gold is stronger than silver. Gold is more resistant to corrosion, tarnishing, and wear than silver, which can be softer and more prone to damage. This is why gold is often used in high-value jewelry and coins that need to withstand the test of time.
Depends on the year and the coin. They may be made out of real silver or gold.
The answer is you don't clean your coins. Cleaning coins is detrimental to the value. Unless they are caked in dirt don't clean them, if they are caked in dirt, clean with soapy water and a towel or sponge and dry.
Not a meaningful question. Gold coins were made from gold and copper without any silver in them. Silver coins were made from silver and copper without any gold.
