Isn't a dollar coin considered change?
If anyone offered me a dollar coin as "change" for a dollar bill,
then I'd consider him to be making a joke.

But there are vending machines that no accept dollar coins.

However the OP wrote:

"For the sake of this program (and David Letterman ;-) , we can
only use pennies, nickels, dimes, quarters, and halves. David
is *not* smart enough to know about 2 and 3 cent pieces."

You guys are not getting nearly technical enough. Have you considered
that there are now the regular quarters plus additional ones
commemorating each state in the Union? That's 51 types of quarters
right there.

But some of those quarters don't yet exist, so we really need to compute N(t), the number of way to change a dollar as a function of the coins in circulation at time t.

Also, there is a new nickel and an old one, there are
wheat pennies, buffalo nickels, bicentennial quarters, etc. All in
all, I think there are a *lot* of ways to make change for a dollar
even if you restrict yourself to pennies, nickels, dimes, quarters,
and half dollars.
