Never say you will not use a coinstar as many banks are no longer offering the free service and are installing coinstars. The times are a changin.
I can safely say I'll never use any service that charges me 10% for a simple counting exercise! It's not that difficult to count change and even wrap it, I've done it in the past.
Harry may be right after all, there really is one born each minute.
They do have to take your home wrapped coins. They are still legal tender. I'm not sure they can legally charge you a fee either unless it is clearly stated in their schedule of fees. If they tried, I'd politely request they provide me with a copy of the schedule of fees that details what they charge for coin deposits. If they have one, I'd be taking my business somewhere else.
When I was putting my pocket change into one of those large bottle banks, my wife and I took several evenings in front of the TV rolling coins. We took $1100 in rolled coin to the bank and they didn't even blink. "Would that be checking or savings, sir?" was about all they said. Yes, it was a few years ago but I don't believe things have changed that much.
Much to my alternating amusement and disgust, my "not for profit" credit union has a coinstar type machine that I believe "only" charges a 7% fee. If anyone needs coins counted, I'll gladly roll and count them for 7%. (You'd get an honest count, too.) All day long. Will I pay 7%? No way in heck!
No business has any legal obligation to accept your money.
