The U.S. has struck $1 coins since the 1790s (with some interruptions) and at about a half-dozen mints, so you need to be MUCH more specific.
The only general answer is that $1 coins dated 1971 and later are not silver and not worth anything more than a dollar. If you have an older coin, please post a new question with the coin's specific date. If you can find a mint mark on the back (a small letter D, S, O, or CC) include that information.
Yes. Canada has used $1 coins exclusively since the late 1980s. Australia and New Zealand make $1 coins. The US made large $1 coins from 1794 to 1935 and from 1971 to 1978. Small size $1 coins have been made in 1979-81 and from 1999 to the present but they don't circulate in many parts of the country because the US refuses to eliminate its paper $1 bill.
Most countries whose currency is denominated in dollars make widespread use of $1 coins so they're definitely being made.
The US is the only exception; $1 coins are still being minted but they're only made for sale to collectors. The reasons are mostly political: the company that makes paper for $1 bills has successfully lobbied Congress to prevent a full changeover to coins, and the failure of the first small-size $1 coins (again, due mostly to political meddling) permanently soured many Americans on the idea of ANY $1 coin.
The dollar coin in use since 1987 is nicknamed the "loonie."
Any dollar coin received as change or from the bank is likely just face value.
