Keep or reroll

You roll a fair 6-sided die and are paid its face value. After each roll you may keep it, or roll again, up to 1 rerolls in total; you must keep the last roll. Playing optimally, what is your expected payout?

Answer with an expected value. First lock in a gut guess with an 80% range, then solve it properly, then watch a simulation settle on the truth.
