I want all coins gone, lol. Mostly because they're a hassle to carry around. Canada has removed the penny from circulation, and it's kind of an improvement because there isn't 5x as many coins anymore :)
The dollar is the new penny. I remember my father talking about buying candy for a penny. Now you need at least a dollar to buy candy. Soon, it will be cheaper to wipe your butt with dollar bills than it would be to buy a roll of toilet paper.
