I believe he should go on the $1 coin the government has been trying to get us to use for several years. One reason that the coin never caught on was that the average American thought that either Susan B. Anthony or Sacagawea deserved the honor (not to mention that no one really wanted to look at SBA's sour puss every time he went to buy a newspaper). With Reagan on the coin, it would be a hit, and Reagan would be in good company with George Washington.
I'd love to have a Reagan dollar coin, but I'd most certainly save them. Don't you think most people would?
