Bi-metallic coins are coins consisting of more than one metal or alloy, generally arranged with an outer ring around a contrasting center. Common circulating examples include the €1, €2, British £2, Canadian $2, South African R5, Turkish 1 lira, and all Mexican coins of $1 or higher denomination. Bi-metallic coins have been issued for a long time, with examples known dating from the 1600s, while the Roman Empire issued special occasion, large medallions with a center of bronze or copper and an outer ring of orichalcum, starting with the reign of Hadrian. The silver-center cent pattern produced by the United States in 1792 is another example. In recent times, the first circulating bi-metallic coin was the Italian 500 lire, first issued in 1982. France, with a 10 franc coin, Monaco, with a 10 franc, and Thailand, with a 10 baht, issued bi-metallic coins for circulation in 1988. India introduced 10 rupee bi-metallic coins in 2009 that are dated 2006 (minted at Noida). France and Monaco also introduced tri-metallic 20 franc coins in 1992. These were similar to the corresponding bi-metallic 10 franc coins, with the addition of a small bronze planchet at the center. These were the only tri-metallic circulating coins ever minted. As well as circulating coins, where they are generally restricted to high denomination coins, bi-metallic coins are often used in commemorative issues. They are used primarily as a way of securing against coin counterfeiting. The manufacturing process is similar to that of ordinary coins, except that two blanks (the inner and the outer) are struck at the same time, deforming the separate blanks sufficiently to hold them together.

GNU Free Documentation License Should the United States overhaul its coinage? Q. I think the United States should do all of the following: 1. In 2009, the first year after the State Quarter program is over, completely redesign all U.S. coinage, except the $1 coin. All Presidents should be removed from coins, and a return to traditional metaphorical representations of Liberty should be re-instated. 2. The dollar bill and two dollar bill should be done away with completely. 3. A two-dollar bimetallic coin should be minted. To the person who said that it would be a pain to carry around 10 $1 coins: If there were no dollar bills, you would most likely be carrying around 2 $5 bills. If you buy something for $4 you would get two $2 coins in change. Bills are a pain to count.

Q. Say you have a bimetallic monetary system (Gold & Silver), (Market VS. Mint Values) If Silver is overvalued at the mint, which coin will run as currency? Why? Asked by Jackson - Thu May 6 23:42:53 2010 - - 1 Answers - 0 Comments A. gold, presuming it's a good enough substitute if silver is overvalued, it does not encapsulate the value of the currency so you will need something else to measure it with also, if silver is overvalued, people would want to get rid of it to maximise their gains before the value of silver falls (if they have a buying strategy and they go by 'buy low and sell high'). Thus, price of silver would be too unstable to measure currency with anyway. Hope this helps Answered by Ingenious - Mon May 10 15:27:45 2010 From Yahoo Answer Search: "Bimetallic Coins"
