Pocket Full

I have a pocket full of pennies

And have no clue what to do with them.

A pocket full of unwanted pennies.

Each penny from a different state.

Dates ranging from 1960-2012.

A pocket full of pennies

To give away for free.

One cent times a hundred makes a dollar.

One cent times one million makes ten thousand.

With a pocket full of pennies,

There are many options to be thought of.

I have a pocket full of pennies.

Can you tell me what to do with them?
