That's pretty average, but still nice, you get some wheats. Some people tend to get higher or lower numbers. I had one bank that had 15-20 wheats a box, before they closed down.
6 Wheats is not a bad score. Which state do you hunt pennies in? I ask, because if I were in NY state, I would have gotten 30 wheats per box average. Just want to see the correlation between the area and the amount of old coins in circulation.
