Coat wallets are more discreet than billfolds in a jacket pocket as they are much slimmer. It is also more practical as you do not have to reach to the bottom of the pocket to retrieve your wallet. More pockets would also mean you can carry more cards and notes (of different currency) which is specially useful when travelling abroad.
