I'm not crazy about the PC origins of the Sacagawea dollar coin, but I do have to admit that it is aestheticly attractive, functional and convenient. (Sure beats that wretched Susan B. Anthony dollar they screwed up.)
Time to retire the paper dollar and move to a coin.
Might as well discontinue pennies while we're at it.
They've become nothing but a nuisance.
I use the Sacagawea coin (when I can get them) but have some problems with it. They tarnish too easily. Also, Sacagawea is a poor choice (but much better than the scowling Susan B. Anthony). Why couldn't they put Lady Liberty on the dollar coin like the examples below? Now that would be a coin that would represent the dollar in a classier manner.
Everyone please send me your dollar bills, (and pennies,)
and I promise to send you something worth less.
You'll be getting serviced while doing your country a service.
