A NOW, ONCE AGAIN, IT'S TIME FOR...

the classic "hidden penny" challenge.  Here are the rules:

• I have hidden my favorite, specialy marked penny somewhere in the NJROTC classroom.  
• It is hidden, but it will be in a generally open, public area.  (You will not search any private areas such as desk drawers, etc.)
• A series of progressive hints will be given.  You will need to solve them (mostly) in order.
• If you find the penny bring it to me.  Since it is my favorite, I'm offering a $10 reward.

Here's your first hint:  If you had $1 then, you would have about $25 now.
