Why are pennies not silver like other US coins?
At the present time, the US has silver colored coins made out of nickel, alloys of copper and nickel, and other metals, but it no longer uses actual silver, which is very expensive. Historically, when coins were first introduced in earlier civilizations, and even in the earlier years of US history, the value of a coin was the value of the metal of which it was made. Silver coins were valuable because they were made of silver, a precious metal, gold coins were even more valuable, and copper coins were less valuable because copper is a less expensive metal, although still expensive enough that coins made out of copper have value because of their metal content. Now the value of US coins is like the value of US paper currency, something that the government declares, rather than being the result of valuable metal content. But out of tradition, the higher denominations are still silver at least in color, and pennies are still copper.
