Big Dump

Unfortunately, the answer is, it depends. Each courier has multiple facilities. Each facility will hold a certain amount of coin. In Oklahoma, I believe most all rolled coin comes from a facility known as 'OKC' which is in Oklahoma City. I'm guessing the facility is owned or managed by a major Oklahoma bank but multiple couriers rent/work/contract out of that facility. Many of our banks will tell you you can only buy in $1000 bags, which are simply bags off a random banks coin machine. Other coin is rolled at the OKC facility and transported to banks and other facilities.

So all regions have their own way of doing things. And even if you figure out their typical process, it will change as soon as one facility runs out of coin. Looking at a few boxes really won't tell you anything in my area. I've had a box with hundreds of silvers followed by a skunk streak of over 40 boxes, from the same bank. In my opinion, the most important reason to keep dump and purchase banks separate, is to maintain a relationship. They may act like they are ok with it(the buy/dump in the same bank) because they are taught to be customer oriented. But when upper level management sees an increase in courier costs, they will find a way to stop you or make you pay for it. This may or may not apply to large national banks.
