Collage in the round -- small format collage coins

I've discovered a new format for collage -- "coins." These cardboard discs are 2 1/2" in diameter with collages on both sides. I made them for a swap, but I'm not sure I can part with them...

Below are the fronts and backs of the first 4 sets of coins I made, each with an assigned theme. 

Theme: Postage stamps
