ELI5: How can banks not accept loose change?

Recently went to my bank, a larger chain, with a bucket of spare change I've been saving for a few years and they informed me that they do not accept loose change. 

So how is it that banks are allowed to do this?

Legally speaking, no one is required to accept loose change, except for very specific situations. IIRC, it involves settling a debt.

Banks actually aren't required to take any of your money, and can refuse you as a customer as they see fit, like any business.
