My Poor Lost Wheaties

[avidbrandy]

So I went to another dump bank today which happened to have a machine the speed of a coinstar, so as I dumped the coins in (this took forever) I skimmed through them.

I found multiple wheats while doing this, and all of them pre-1930s. I'm horrified. Is there any way I can prevent this without hand sorting my zincs too? I currently do a zinc accept and then check the coppers with a copper accept.

Edit: Just checked my pocket. One of the wheats I saved from the coinstar was a 1911.

I do a zinc accept then sort both the zinc accepts and zinc rejects vs a copper, separately thus if my zinc rejects have pre-1940's they will be rejected as coppers, without any zincs around to hide them. Do you do the second sort with only 2 bins or do you have zincs, zinc accepted coppers, coppers and rejected as both zinc and copper? Maybe I am not describing this correctly.

Gosh, I hope this makes sense.
ETA: What a cluster F I created here... Really, wtf?

yep

I know kind of funny, but...
Zinc accept, yes or no
Copper accept zincs, yes or no, zinc rejects, yes or no.
Glad, I could make you laugh, while trying to demonstrate my point.

I've tried messing with the potentiometer a bit. I don't want to go through my zincs again because there's so many. I do about 10 boxes every time I sort and it just adds a lot of time to it.

[Chief]

I always double "cross" sort to ensure the purity of my stash. Double the time, but higher purity of coppers.

This is news to me. Is it common for pre '40 wheats to be accepted as zinc? Why is this? Are they so worn down that they are too light or something?

[avidbrandy]

partially, but also there was a lot of variation in the medal used back then. I know the ryedale guy has something about it on his site.

[Chief]

I would say, if you are only using two bucket/containers for sorting via a Ryedale and running the zinc and non-zinc together during the double sort, pre-1940's will end up with the zincs. You almost need 4 separate containers to ensure that this does not happen, or two containers, with both emptied between sorts of zinc accepts and zinc rejects (mostly copper, few 1940's, sometimes missed zincs, and rarely IH's).
In my opinion, zinc accept then running the zincs and zinc rejects in copper accept with 4 separate containers (or 2 containers emptied for each of the 2 sorts) is the way to go.
It is almost worth it to not double sort the first sort zinc accepts. Resorting these against a copper, for me, only yields about 4 coppers per $150fv in pennies.
I'd almost rather lose 4 coppers than one pre-1940 wheat.
