This is the third attempt to reintroduce dollar coins. The past two times the coins were ugly (Susan B. Anthony & Sacagawea), about the size of quarters, and they tarnished so they began to look like dirty pennies.
At least this time they are putting presidents on them. But they still make them too small, and they tarnish. If a dollar coin must be circulated, I say bring back the old "silver dollars" that we had when I was a kid. They were big enough to distinguish them from other coins, and they held up well.
