Will banks cash coins for free?

As a concerned citizen, I am wondering about the practices of banks when it comes to cashing in coins. Do banks typically offer this service for free, or is there a fee associated with exchanging large quantities of coins for cash? Is this process different from bank to bank, or are there industry-wide standards in place? Understanding the cost and convenience of this service would greatly help me in managing my finances, so I'm eager to hear your insights on the matter.
