Yes! I have a bank that will order them for me from time to time. I haven’t found any silver in them yet.
I think this particular bank uses their own cash room for large dollars. The way I understand it is that all branches of this local bank send their large dollars to their own cash room at the main bank, once there they are put into a coin bag and held onto until its full ($500). Then they send it out or send it to my branch for me to pick up. It’s not they they “order” them every time I ask. The head teller calls the cash room to see what their inventory is and if there’s a full bag, they send it out.
I think I haven’t found any silver in them because there’s too many hands that handle the coin until it gets to me. But I keep trying.
