Good idea! One of the things I like todo is track the box types I get from various banks. Some are clearly labeled 'brinks', etc and I also track the years they produce much like the "cent project" (which I had a great interest in, too bad it fizzled). I can use these results to identify the banks/suppliers to one with the most potential (oldest average coins).
An idea I saw that I'm going to try as well was to get coins from small town banks, the idea was that coins were more likely to be recirculated longer in a small area.
