If the coin rolling companies effectively killed the CRH hobby, would they not also be taking a hit on their profit margin since less boxes would be ordered and less bags sold back to the companies? If I understand how their business works, the coin rolling companies make money on both ends of the deal. So not only would them culling silver have to pay for the man hours needed, the equipment upgrades, but also would have to make up the differences going both ways of lost boxes ordered and new bags of coins coming in. Before anyone says that the amount of money charged by the companies is inconsequential, consider that those charges are how they are multi-million ( I dare say billion) dollar companies. Because of that, I am sure that they do extensive surveys to determine if a bank or other outfit is ordering more than a normal amount of coinage in certain denominations. It really wouldn't surprise me if they had a map of their area and could point out where CRHers are.
As an addition, they would also have to determine if the offset in profit from the three factors listed above would be cost effective and provide the needed returns with a dwindling supply of silver in the system. If the companies culled, they would effectively acquire all of the silver inside a year. Which would mean a permanent decrease in the extra boxes ordered for CRHing by that time as well. If the silver were left in the system, realistically, CRHers probably would take a minimum of 10 years (probably longer) to deplete the silver. Would the companies get enough in silver and would the price be high enough in the next year to offset the loss in revenue for the next 10 years or longer?
