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.
And sometimes the paper readers on such machines are
defective, making a dollar coin acceptable as change for a
paper dollar.
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."

Does the 293 ways include the dollar coin or not?



Maybe. Or maybe it includes the original dollar. It's not my puzzle specification to say. What's certain is that there are 292 ways to make a dollar using only pennies, nickels, dimes, quarters, and half dollars.
