People will pay crazy prices for wallets. I still have a lovely Mark Cross wallet, a memento of "the days of wretched excess." I am very happy with my little Smathers and Branson card case with the Texas flag embroidered on it. It holds my license, my debit card, my credit card, my insurance card, and my frequent buyer card for Waterloo records, everything I need. If I used a folding wallet, cordovan might be a good choice, but my little flat card case is unlikely to wear out. I have to say for shell shoes I really have found Alden Madison Ave. terrific. I'd probably ping them for one.
BTW, on the subject of rich people not carrying wallets, I used to work for a multibillionaire. He hit me up for a couple of bucks for dirty water hot dogs in the city and mooched dozens of Titleists for mulligans on golf courses he owned. Still, I kind of miss him.
