Last Spring my favorite local coin dealer showed me a hoard of unsorted Canadian mostly pocket change plus circulation pulls that he just wanted 'off his desk'. Included were ~100 rolls of pennies from the 1920's up to the late 1980's. The total price was 80% of face. It was ~50 pounds of metal that I had trouble lifting. I questioned my sanity at the time, but now it seems like a prescient purchase. Thanks to the information you folks are posting, I will have at least a rudimentary idea of what to look for whenever I find the time to search this mess.
