When you say year pennies, I'm assuming that you mean what years on the penny make it valuable. Well, the grand-daddy of all Lincoln pennies is the 1909-S VDB penny. You can find the initials between the bottom of the two wheat stalks. (1909 was the only year that had the initials VDB (Victor David Brenner) between the bottom of the two wheat stalks. Also, all the 1909 pennies are worth quite some money, but not like the omg I'm sooo rich type.
Other key and simi-key dates are the: 1914-D (only 1,193,000 minted)
1922 no D or S on it (mintage unknown)
1931-S (only 866,000 minted)
Here are coins that the mint made by accident: 1955 double die (doubling in
everything)
1972 double die
Hope this helped!

I don't uderstand you question. If you are refering to how many pennies the US has made i don't think that there is a way to figure that out due to the fact that no one knows how many pennies were made each year in the mints early years.
The US never made silver pennies. In 1943 the US made steel pennies. These are often mistaken for silver pennies.
it depends wheather or not you are interested in them and think they are valuable.

There are many years that have valuable 1 cent coins. For Lincoln cents, this usually will involve a combination of the year and the mintmark -- a small "D" or "S" below the date.
