Silver Coin Detecting Roll Machines

I'm sure this has been asked here somewhere before.
Do the coin rolling companies (Brinks, Loomis, etc..), coin sorting and rolling machines detect and pull out/eject silver coins?

They probably have some machine that weeds out slugs and foreign coins that would also remove silver coins and obsolete US coins such as 1943 cents. Hopefully, someone here who works for one of these companies will comment on their process.
Worry is the interest you pay on a debt you may not owe.
The Coinstar often rejects silver dimes... Not sure if it always does. I would think those companies have some sort of detection capabilities. Cheers, RickO
During the changeover from silver to clad in the mid-1960's, once there were enough clad coins in circulation to carry the load, the Mints began pulling silver back out of circulation by running dimes and quarters through weighing machines that had originally been ordered to catch missing clad layer planchets prior to striking. By tweaking the expected weights they were able to separate the heavier silver coins from the clad and just keep the silver ones.
This was fairly labor intensive, and they discontinued the sorting when the percentage of silver being recovered fell too low to be cost effective, but not zero. Considering how little silver there is out in the wild today, there is no way that it could be cost effective for a simple coin depot to weigh each coin going through.
And all of this makes me ask a question of the Coin Star checkers. The machines reject silver coins because they are heavier than the normal clad ones. Do they reject pre-1982 cents for the same reason? I ask because I just half an hour ago got this Unc-ish 1960-D cents in change at a Dairy Queen, complete with fresh coin wrapper scratch. Would Coin Star reject this?
Having trouble with pictures.
A simply brilliant reply and explanation Tom, THANK YOU!! 👍🏻
I look forward to the answer of your Coin Star question.

I'm pretty sure they have ways to sort copper, I would think they can sort silver.
Yes, coin machines sort by size and weight. The 90% junk gets kicked out at Brinks, Loomis, etc. Just like it does at the coinstar. Junk weighs more than clad. RGDS!
The whole worlds off its rocker, buy Gold™.
Thank you for the additional feedback. That's most likely the reason I'm not finding much silver in bank wrapped rolls. I would only make one change to your statement. I would say: "silver weighs more than clad" not junk. The junk is the clad! 👍🏻 😉

I'm not so sure about the coin processors sorting out the silver coins, yet. Like just last week I found 15 silver dimes in a batch of MWR. Although I did heard that hunters in AZ may disagree, so it may be regional.

I don't think it has anything to do with weight today.

For $70 or so you can build a coin comparator, i did it to sort copper cents but it could also sort out the silver, based on size and metal content.

In my quarter Coin Roll Searching, I have found silver (6 this year) found Canadian coins, slugs, nickels, and other Foreign Coins, from rolling companies, so I say no they do not pull silver...
The only thing I found in a COinStar machine this year was a clad dime that had been exposed to some sort of corrosive environment. The cu-ni surfaces were pitted, the the copper core on the edge had been eaten away maybe half a millimeter so that there is a groove around the edge. This of course made the coin lighter, and I believe that that is why the coin was rejected.
I have a Rydale machine that sorts copper pennies for me. However, I need to search the zinc for shell brass wheat cents, as the alloy falls out of tolerance. It's a pretty nifty little machine, but I don't use it as much as I used to.
I am a newer collector (started April 2020), and I primarily focus on U.S. Half Cents and Type Coins. Early copper is my favorite.
I remember armored truck companies and banks using clear plastic rolls for dimes, quarters and half's back during the changeover in 1965.

btw What is the percentage of copper/zinc cents are you seeing in rolls these days. About 10 years ago it was about 20% or so copper in my area when I stopped checking.

That would be a great way to spot silver today! 👍🏻 😂

@metalmeister It's still around 20% in my area.

I always check my own rejects to make sure they’re not a wrong planchet error.
I suspect that, if some coin rolling companies pull silver, certainly not all do, or at least not in all areas. I just hit a "jackpot" on a box of halves from Loomis: 13-1964 Kennedys, 4-40% silver Kennedys,12-Benjamin Franklin halves and 4-Walking Liberty halves. Obviously, this is a very rare occurrence, but there are still some silver coins out there in the wild.
Back when I was CRH for W quarters the boxes of old coin rolls would yield on average one Silver quarter per box. 😉🤑🤑🤑
