For a more observable example, think about sorting American coins. A dime is the easiest because it is the smallest. Quarters are much larger so are also easy.

A dime is the easiest because it is the smallest. Quarters are much larger so are also easy. In the middle are pennies and nickels which are the hardest to separate from one another because they're so close in size.
