Now that I have a Ryedale Sniper, I made my first run at automated sorting. I picked up a couple of boxes of $25 from my bank and got to work. This is what I managed:
US Copper (including wheat): $11.11 (face)
US Wheats: $0.17 (face - no unusual ones)
Canadian Copper: $0.13 (face)
Total copper: 1124 coins for a total of 22.5%. Not bad. The number of wheats I pulled was actually better than what I had been getting previously (maybe one in every $10).
I've got to run to the bank again this morning, so I'll pick up another $50 and see what I can find this weekend.
