I think someone else posted recently that PNC cut them off from boxes of halves since PNC is getting too many halves dumped on them. I guess PNC is assuming that their boxed coins are coming back to them rather than just getting dumps that were bought from another bank. Even so, the reasoning doesn't matter. The point is that PNC seems to be tightening up against CRHing, at least for halves (if the recent poster was right). Unloading dumped coins on them will only make it worse. In my area a number of the PNC coin counters, when they have them, are either calibrated to not take halves or are permanently out of order. I know of only one or two PNC counters that take halves near me. I try to spread my dumps around, even if it means dealing with TD machines that only take $100 before a bag change. While I use PNC to dump, I don't abuse them, for fear of losing a dump bank.
