None that I know of. The idea behind having a different metal in the core of any coin is to increase the coin's structural integrity. Gold is quite soft and though valuable, would make a poor choice for any coin. You may be thinking of a so-called bimetallic coin. Many countries issue these coins, but they're made of brass and copper-nickel, not gold and silver. Examples are the Canadian $2 coin, the European €1 and €2 coins, and the British £2 coin.
The €2 piece is the most common bimetallic European coin with a silver-colored ring and gold-colored center.
No circulating European Coins contain gold or silver. The silver color is copper-nickel and the gold color is (usually) aluminium brass or a similar alloy.

All coins, even gold and silver, will tarnish, but rust is iron oxide, so only coins with iron in them will rust. The only ones I can think of are the steel 1943 US cents and some European Coins from the WW2 era.
Clad coins are regular coins, all US dimes, quarters, half's and dollars made since 1965 to date are "clad". Each coin has a center core of pure copper and a layer of copper-nickel or silver on both sides of the coins. The only coins made for circulation after 1965 that had any silver were the 1965 to 1969 Kennedy half dollars but they are 40% "silver clad" coins.
Alot of coins from many countries are as you are describing, if the metals are actually gold and silver that narrows it down, Mexico has made some really nice dual-metal coins with precious metals. But must gold ans silver coins I have seen are bronze and aluminum.
All coins come from a mint. Casino coins are sometimes solid silver.
What are old european coins beginning with t?
Roman coins did not lead directly to American coins. European coins came after Roman ones, and people from Europe came to America and brought European coins with them, and when they made their own, they kind of copied the European ones.
There were proof sets made in 1974 and 1975 where all 8 of the coins were silver, and proof sets made during those years when none of them were silver. Assuming that your coins are in a set, check the 1 Cent coin - if it looks silver, then all the coins in the set are silver; if it looks bronze, then none of the coins in the set are silver.
Just recently with the advent of bullion coins such as the American Silver Eagle. Coins intended for circulation were never 100% silver because silver is simply too soft of a metal for coinage. They were 90% silver in American coins until 1964 for dimes, quarters and half dollars, but other than bullion coins, no coins are made of 100% silver.
No British circulating coin has contained any silver since 1946. From 1919/1920 to 1946, all British silver coins contained 50% silver. Prior to 1919/1920, all British silver coins were made from sterling silver or, 92.5% silver.
No, coins are not an element. Some coins may be made of nearly pure gold, silver, aluminum, or other metal elements, but most present-day coins are made of various metal alloys, often with different composition on the inside than on the outside.
Yes they are silver
