If they were all the same size, I'd be going nuts. But wouldn't it make more sense for them to increase the size of the coins with the denominations? Wouldn't that make it easier for everyone? And why does the dime say "One dime" versus "ten cents"? What do tourists do when they first come to the US and are figuring out the coins and see that? "What's this dime thing? I thought it was cents! Ah!"

Those darn Illinois people. *shifty eyes*
I wonder how much the two pence coins costs to make. Cause they're really big and hefty.
