Dimes are the new Pennies

It's the strangest thing but during my walks, I find more dimes than I do pennies now a days.  On my walk in this morning, I found 4 dimes but only a single penny.  A couple years back, I'd find pennies by the ton.  Now it's like folks don't care about dimes anymore, like they used to with pennies way back when.

Or do more folks have more holes in their pockets?
