Hang in there. Just a speed-bump. Do some dimes while you wait for halves, there's usually something in those boxes, and they're easy to pick up just about anywhere.
What denominations are you talking about? I would def switch up atleast some ordering, get some Dimes (or even nickels) and search them. Get atleast on roosie dime in your pocket... I did 10 halves boxes of skunk. Then I hit 2 90% and 34 40% in my last 5 boxes.
