We did that years go and only have dollar coins. If fact we went further and minted two dollar coins as well, both replacing paper. I'm sure if I looked I could find first year coins and they wouldn't look worn at all.

We call the dollar coin a '' loony '' because it has a loon on the back side. The two dollar coin ended up with '' toony '' for obvious reasons even though it has a polar bear on the back side. The Queen is on the front side.
