I have a nickel with the president and a ship on the back but can't read the year.?

Turn the coin over; the date is on the front. Your coin is called a "keelboat nickel" and was minted in 2004 as part of the Lewis and Clark Bicentennial. It's really a boat rather than a ship and was one of the more recognizable means of transport used by the explorers.

The mint strick hundreds of millions of Lewis and Clark nickels and nearly all were saved from circulation. They don't have a lot of extra value unless you have a special proof version from the San Francisco Mint. Even then it may only be worth $2 to $5.
