Even when they were somewhat popular in the early 2000s, people were always pleased to get them. I don't know why people insist on dollar bills that are always greasy and frayed. Eliminate the dollar bill and go to dollar coins. Eliminate the penny as well.
Unfortunately, pennies cannot be eliminated so long as there are state and local sales taxes.
That’s the real reason dollar coins never caught on. People would have used them no problem if dollar bills had been take. Out of circulation at the same time.
