<prompt> Human: What is the most cost effective way to cash coins?Ive been saving loose change for nearly half a decade now and would expect to have upwards of 2k in coins. Should I roll them all then bring them to a bank? Should I bring them to a bank in the buckets theyre in? Should I just suck it up and use the machines at at my local supermarket?  <response>: Some banks have free to use coin machines if you have an account with them.Thats what i used when i had 350 in change nothing larger than a quarter so no loonies or toonies
