This is for the second edition of Ponzi Scheme.  I use game money cards from The Game Crafter.  

I suggest having the funds layer as the bottom layer if you store your games vertically.

I will be adding inserts for just the base game in the future.  I plan on the bottom layer being the stocks, paper money, and start cards.  Each is in its own removable tray.  The funds card will be moved to where I have the paper money now.

V2 update:
In the Stock Paper Money folder is an insert for the stock game using paper money.  It can be used with the plastic money also.
