So, my handbag, as I've been corrected

, is black microfiber, about 9.5" wide, 10.5" high and about 3" deep. It looks similar to a Messager bag which is probably why my wife lets me carry it. It has one thin zippered main compartment where I keep my purse. It has 2 thin magnetic closure pockets on either side of the main. It has another zippered pocket that hangs on the front that's not as wide as the main body but it's as thick as the rest of the handbag combined. It's the place where keys, lip balm, ear buds, and any other larger items go.
The thing I'm having trouble with is what to do with coins. If I drop them in to any of the pockets, I have trouble fishing them out when I'm standing is the checkout line. The purse that came with the handbag has one zipped compartment that fits bill well and it has some credit card slots inside. With bills and receipts in it, I'd have trouble fishing out coins too.
I'm thinking a separate coin purse that would fit in the outer pocket and might be the solution, but it may be awkward fumbling with 2 purses. On the other hand, it might be kind of hard to find a purse hold bills and coins that would still fit in the thin main compartment.
For now, I've been carrying my coins in my pants pocket. Someday I hope to be wearing skits and dresses out. Some skirts and most dresses don't have pockets.
Does anyone us a separate coin purse or is it better to have a combined purse?
Paulie.
