Back on your Nov. 30, 2011 post, +James Salsman
and I were having a discussion about how coarse the denominations of the dollar should be broken down and which coins are really necessary. I'd be interested in what research the Canadians did into this topic, and if they had any findings about other coins beyond the penny. If you happen to come across data/research the US Treasury has done, I'd be glad to hear about that too. Your comments between 3:24 and 3:32 allude to this discussion, it's the elaboration I'd be looking for.
