... So if you used a 1929 coin as a comparitor...
I use a Zn cent as the reference. Anything that matches is dump material. I am Ok with the fact that this approach causes the comparitor to work 3x as often as if the reference coin was Cu (75 "matches" out of 100 instead of 25 - assuming 25% of cents are Cu).
Anything that rejects against the Zn reference is either Cu, Canadian, or other.
I then send whatever rejected against the Zn reference through a comparitor with a Cu reference. The match from this comparitor are 1944-1982 brass cents. The reject from this are pre-1944 cents, US dimes, and any foreign. I always hand search this bin. I used to had search the accept side of this comparitor for common date wheats. Now, I mostly stack them for possible searching later.
I cobbled a contraption (
) that feeds from a hopper into the first comparitor whose reject side then feeds into a second comparitor. It's not pretty - I call it the Franken-Sorter.
That config gives me 3 outputs - Zn dump, brass keepers, everything else.
If someone wanted to recreate this approach using Ryedales, it could possibly be done by feeding the output of the Apprentice into a Sniper. I think the question is whether a handful of early date wheats is worth the trouble and expense.
