There isn't an answer to this question. All banks are different. What would be acceptable at one may be unacceptable at another. Even getting clearance from the manager ahead of time does not guarantee that things won't change. Different branches of the same bank can have different rules. When I first began to CRH I lost a dump bank. Before opening my account, I honestly told the manager what I do and that I wanted to run $500-$1000 a week in halves through their coin counter. She said, "No problem." Well, about 2-3 months after me dumping around $500 a week there, I was told I could no longer bring in coins. Another dump bank of mine has told me on numerous occasions that I can bring in as much coin as I want, as often as I want. I've been dumping at least $1000 a week there for several months and so far they have been true to their word and I have had no problems whatsoever.
