I always run the zinc pile back through with a zinc penny as the comparison and check the reject side. Always a few wheats there.
But in the same time that you would run the zinc side through a second time, you could be running raw cents through (A new box) You will get 10 more wheats from the new box instead of getting that 1 wheat you might find on the zinc side. Just not worth the second pass. If you only had one box, sure, why not. But since the supply of new cents is endless, it still makes sense to watch the zinc (reject) side while sorting the first time, grab the cents that come out on that side that are real dark and check them quickly AS you sort, and then NOT go through the zinc side again (Which would be 85% of the box again, for my boxes) but do a NEW box, and get MORE wheats than doing the same box a second time.
Make sense?

Sort with a zinc cent in the comparator first and then whatever is rejected is not zinc. Then sort the rejects with a brass cent in the comparator and whatever is rejected is not brass. Then hand-sort the rejects and look through the brass (accepted) cents for brass or almost-brass Wheat cents (1944-58) and Canadian cents (1996 and before). The rejects from the brass pass should contain bronze cents, including Wheat cents from 1909-1942 and some Lincoln memorials from later years which you can put back with the accepted brass cents by hand. There may also be Indian head cents, dimes, steel Canadian cents (1997-2012), steel U.S. cents (1943), Euro 2 cent pieces, cents from the Bahamas, Bermuda, etc., corroded zinc cents, and other anomalies in the rejects from the brass pass.
I keep the sensitivity dial turned up a bit on both passes, since that should raise the bar for what is accepted and cause more coins to be rejected. I've seen the Ryedale make mistakes a few times, usually bronze wheat cents being accepted as zinc in the initial pass, but this is rare. I've never seen it miss an Indian head this way.
Brass U.S. cents are 95% copper, 5% zinc and bronze cents are 95% copper and a mixture of zinc and tin for the remaining 5%, usually.
It is much faster to look through cents that have been (mostly) sorted than to sort all of them by hand...
I "sandwich" a layer of coppers between a couple of 12" x 12" pieces of plastic (polycarbonate I think), clamp the plastic together with three small spring clamps, scan the reverse of the cents, flip the clamped plastic, and scan the reverses again. This is an easy way for me to scan 75-100 cents at a time. The thin plastic is from the window department at Menards building supply.
