Im not sure, but it It separates all indian pennies and wheats from the copper ones.
It could be done with optical recognition. It cannot be done with the alloy detection technology like what the Ryedale uses - not all wheats anyway, just early wheats.
As Bigheed says, you can discriminate the bronze cents (Cu, Sn) from the brass cents (Cu, Zn) if you tune the comparator for that.
They were Bronze from 1864 - 1942 so IH and early wheats can be detected with a high sensitivity setting.
After 1943 they were Brass until 1982 when they became Cu cladded Zn.
so then you dont think it would be worth it for him to try to get them produced to sell?
If he has a system that does it, there is likely a market for it among the CRH'ers. I would like to know how it works. It might be that it detects all pre-1943 which would appeal to some. If that is what it does, there are already known solutions for that. See my post above.
I would buy one.Does it just filter out all copper or only wheat cents?and how would it know a 1944 wheat from a 1964 copper.
Some members run their coins through their sorter twice. Once to get the brass cents and then again to get the early date wheats (and IH's).
Like some other members have done, I made a sorter that has two stages. For mine, the first stage uses a Zn cent as the reference. Everything that matches the first stage gets dumped (modern memorial errors included - ie WAM). If it is not Zn, then it is either Brass, Bronze, Steel, or Foreign. All of that falls through to the second stage that uses a Brass cent as the reference. Those all get hoarded for possible hand processing later (to pull late date wheats and Canadian brass). Whatever doesn't match the 2nd stage gets hand processed. That is where I find early date wheats, steel wheats, foreign coins (Canadian, Euro, etc), and US dimes.
What do you consider big bucks? And what would you pay for a machine like it?
Without a price point there is no point asking someone if they would buy it. Big bucks? I highly doubt it would be a successful venture.

i would rather just buy a ryedale, that sorts out coppers, and inside the coppers are wheat cents, most of the time, but like others have said, some older wheats get thrown in with the zincolns.
plus the ryedale does double what this product would do, unless the product is real cheap, i don't think people would buy it.
