I think my CU is sorting Cu

I went one of my Credit Unions this morning (that I don't go to very often) to dump my built up return pile.
This is the first time I have used their coin counter, and not only was it slow (Still much faster than rolling by hand), but I noticed that there were 2 lines for the $0.01 denomination. My first thought was that the penny is more common and perhaps they had a separate bin or bag for when the first is too full and it counts it separately. Then, I thought I saw a copper in the dump tray and then remembered that there might have been 1 or 2 in there that I missed or were just too ugly for even the ugly pile.
All said and done, out of 5,500+ cents dumped, there were (5) in the first $0.01 line and (5k+) in the other $0.01 line. The teller said nothing, didn't even seem to notice the vast difference on the return slip.
2 Things:
Not bad for hand sorting (99.9% Accuracy), and
Have any of you experienced this, and what was the reaction from the Bank or CU?
