Your coin has the words "United States of America", and a date and a denomination on it, therefore it is most likely an official US Mint issued coin. There are several types of official mint issued coins, the most common being the regular issue coins. These are coins struck for commerce every year. In the last few years there have been over 10,000,000,000 regular issue coins struck each year! Nearly every coin you have ever spent falls into this category. These coins outnumber all other categories by hundreds to one. Nevertheless, many regular issue coins are extremely rare depending on the date and mintmark combination. All regular issue coins have a denomination printed on them (unless they are too worn) and this provides a good place to start in figuring out what kind of coin you have.

The other kinds of official US Mint issued coins are collector sets (like mint and proof sets), commemorative coins and bullion coins. Bullion coins have only been made by the mint since the mid 1980s. The majority of early commemoratives from 1892-1954 were half dollars, while the majority of modern commemoratives from 1984-present are dollars. There are of course several exceptions.

If you are unsure which you might have begin with assuming it is a regular issue coin. If you can't find it there, you can always come back here to see if it is something else.

I think my coin is:

A Regular Issue coin used in every day commerce. It is a half cent, one cent, two cent, three cent, five cent (nickel), ten cent, twenty cent, twenty five cent (quarter), fifty cent, one dollar, or gold coin.

A Proof or Mint set or a single proof coin.

A commemorative (choose pre-1980 Commemorative or post-1980 Commemorative)

A Bullion Coin (1986 to present)

Miscellaneous. It has "United States of America" but it's not a regular issue coin, nor does it seem to be one of these other types.
