With extensive magic, either every coin is a magic item that sizes itself, or perhaps everyone uses counter checks written on resizing paper.

Unless people tend only to deal with others of similar sizes. Faeries only do daily commerce with Faeries, titans with titans. The middle groups can probably get by with human sized coins. Faeries and titans could deal in bulk from the mid-folks, where transactions would be in large enough quantities for larger coins/bars to work, or banker-level transactions.

There's a lot of issues the more you think about the situation. Groups that cohabitate but don't interact much is much easier to comprehend.

Sounds like an opening for a money-changing profession. I expect letters of credit and accounts to be a lot more common - instead of carrying a lot of cash, you have accounts with your usual vendors and settle up every so often. Of course, illicit transactions get a lot more difficult since the trust isn't there, and people on the down and out or with a bad reputation are also up a creek.
