As I have understood it, the carriers DO NOT own the coins, there for they can not cull anything at all period, this has come up several times over the years. HH, Maverick.
I have heard this since I've been here, but over the years I have come to not believe it. Its not cost-effective, nor does it pass the "common-sense" detector.
What I believe happens - what makes sense
to me - is that essentially the couriers count and then buy the coins from the banks. Then they sort and reroll said coins into boxes to sell to other banks. I have bought MANY bags of coins off coin counters. Most of these bags have had the banks' deposit info already filled out.
Without fail, every single one was made out for deposit into The Federal Reserve Bank. Not Brinks, not Loomis, but the Fed. Now, we all know that the coins do not get shipped back to the Fed. Therefore, I believe that the couriers count the coins, and then make a deposit in that amount into that particular bank's account at the Fed, thereby essentially "buying" the coins. They then reroll/rebox and start all over. That makes sense. Having separate vaults for every banks' coins does not. Having to sort and reroll every banks' coins separately does not. If the couriers merely "held" the coins for the banks, there would be no reason to deposit them into the Fed in the first place.
While its naive to say that no coin courier employees have ever culled some silver, I do not believe the companies will do it for company profit (unless the price of silver really skyrockets) as it likely would not be cost-effective. However, we all know some coin counters reject most to all silver - not as an intentional act, but a by-product of rejecting non-U.S. coin items. It would be very naive to think that some of the big industrial machines that the couriers use do not do the same.
Search out some of jrf30's previous comments about something similar. I certainly believe what he had to say as he gains nothing by lying. I also remember another poster from years ago that ran a smelting business (jewelerdave or something like that maybe. Not sure on that one but someone will remember). He said the guys that worked in the local Loomis facility were selling him silver that they "swapped out" all the time. Again, I believe that story as well. Maybe I'm the naive one, but I don't think so.
Some of you that have those huge skunk streaks may live in an area where the coin couriers' machines either purposely or inadvertently reject silver. In fact, I'd say its likely.
