^ most denim pockets aren't lined with denim, its usually a cotton or canvas fabric. but you can never be too careful! As a guy i always use my front pocket, I like my wallet in front of me so i can 'see' where it is and cant be snatched easily. I find that it makes you care more about the wallet. However, i do agree that a hard wearing leather (like epsom) must be chosen becuase men are more hard wearing on thier items.
As for models, mens wallets are very secretive at H! i have seen very few models in store and on the net. more often than not they are CC wallets, very few have coin pouches. you are looking at roughly 1k+ for a regular leather wallet 2k for exotics. SO they dont come cheap. Personally i use a small CC wallet which is dying on me and when the right model comes in im going to get a PM agenda, the side slots are perfect for CC's. However you are limited to only 2 slots, but the price is very affordable at $270. and you can still get a blank page insert if you want to jot things down. Just an option, i dont think it sounds right for your hubby but I threw it in the mix.
