It depends very much on what the coins are made of and how much use they get in comparison to other denominations. For example, in the US pennies tend to stay in circulation for about 10 or 15 years on average, but because they're low-value they tend to be stuck away in drawers, lost on the streets, etc. Quarters are more valuable but get a lot of use so they also tend to disappear from circulation after about 15 or 20 years, although it's not unusual to find some from the 1960s. The new brass $1 coins get less use and are expected to stay in circulation for 30 to 50 years.
It also depends on the coin's design. When designs are changed some people begin to save the older designs so those coins may disappear from circulation a bit faster. By contrast, before England switched to the decimal system their penny had essentially the same obverse (front) design for well over a century. Nothing special stood out and old ones stayed in circulation, sometimes for 75 or 80 years.
