Hey Havok, everybody does it a little diferent so, I'll give my advise/opinion, I have 18+ branches that I deal with to do my dumping (for bags and rerolling), it is more work and driving, but it keeps it low profile for me, as much as I would love to just start dumping 5-6k a week at 1 branch to cut my travel down, I feel that it would jusr bring to much attention. I'm not as much of a nusiance if I'm just leaving 2 boxes or 4 bags ( my rule, never dump more than you can carry) at 5-6 branches 1 day of the week and the next day visit another 5 and so on and so forth, plus you can search more this way.
Now the bags, I just asked one day when I was in there about bring in coins in bags and if it would be any easier for them if I did, she said that it really didn't make a diference ( dumping rerolled coins I did 1000 a dump, bags I could do 2000, this was the advantage) so I asked if I could have some bags and try it out a few times, she gave me some and I just keeped bringing my bagged dumps once a week and would ask for a few more bags every time I went in.
Also, I have a lot invested in my dump bank, and the same account for 25 years now, this helps me a lot too. Good luck, HH, Maverick.
