The face side of the coin
nope.
one cent
There is no special reason for this. The way the presidents face is not determined by any law but is determined by the designer.
It means you are 1¢ richer. Which side is facing up makes no difference.
rub your fingers on the face side, if there's oil present on your finger or face it will make the copper shiny. If the face turns shiny, it's made of copper.
It is worth five cents.
Yes. It is worth a dollar
There's no such coin as a "two cent penny" because a penny is either a 1p British coin, or a 1-cent coin in the US, Canada, and several other countries. If you have a 2-cent piece with a map of Europe on one side and a picture of the Netherlands' queen on the other, it's a common circulation coin worth face value only. If you have anything else, please post a new question with the coin's date.
25 cents
The head of a penny is obviously the queens head, and the tail is that thing on the other side of the penny.
Most likely the reverse side of your coin has been sanded smooth and has no value other than that of the copper in it.
