What is the value of an 1841-1845 us 1 dollar coin?

It's not from 1841. Those are the dates that President John Tyler was in office. It's a current circulating $1 coin in the Presidential series, and is only worth $1. Feel free to spend it.

Four designs are issued each year depicting each president in the order that they held office. Their dates of service are shown below their portrait, and the coin's minting date is on the edge.
