Who is the 10th president on the US 1 dollar coin and what is its value?

The 10th coin in the Presidential dollar series carries a portrait of John Tyler.

Like all Presidential dollars, it's only worth $1 in circulated condition; feel free to spend it. Your bank should be able to supply you with as many as you want for the same price each.

The front shows the dates he served as president, 1841-1845, and the edge shows the year it was minted, 2009.
