Based off the advice that I received from poofrabbit, I altered my previous design of the adjustable money clip with a coin that acted as a screw.  Now in addition to adjusting to the amount of money that you have, it can also hold coins as well!  My old design can be seen at https://www.instructables.com/id/Adjustable-Screw-Money-Clip/.   It has detailed SolidWorks instructions on how it was CADed.  The last picture shows the original version of this project.

To change this design, I created a third part (the second picture) adjusted the position of the screw so it would fit into this part.  I made sure that the coins would fit by using the website http://www.usmint.gov/about_the_mint/?action=coin_specifications to size them.  I adjusted the tolerances of both the third part that I created and the space for the coins to ensure that everything would fit together.

I used the exploded view feature on SolidWorks to create the bottom picture.
