I went to the post office and the vending machines there return change that’s a dollar or more in $1 Sacagawea (sp?) coins. The only things on the planet that use them. So, randomly, I decided to try one on the vending machine at work, even though the machine said insert nickels, dimes, or quarters. And it worked! I dunno, I thought that was cool.
If you ask me, they should just get rid of one dollar bills so people are forced to use the coins. They last way longer so it saves the government money on production costs, I think. And they should just get rid of the penny and nickel entirely, and have dimes be the lowest coin. Nickels and pennies – what a waste of resources.
