I've long been an amateur U.S. coin collector, and have always been interested in the changes that they've gone through over the years. One thing that has **not** changed over the last century is the number of different ways to make change for a dollar. And that's what leads to today's *Free-for-all Friday *challenge at the mentalfloss.com **Brain Game.** Good luck:

How many different ways are there to make change

for a one-dollar bill using some combination of

half-dollars, quarters, dimes, nickels, and pennies?

Not every coin type need be used in every combination,

but each combo should total exactly $1 in coins.

Here is theANSWER.

**How many different ways are there to make change for a one-dollar bill using some combination of half-dollars, quarters, dimes, nickels, and pennies?**

**ANSWER: ***292.*

*Here's a years-old (but still great) Web page that provides details. Note that my question did NOT include the possibility of a one-dollar coin as being valid change for a one-dollar bill. **Have a great weekend!*
