I'd reported that my wallet was stolen. It appears the thief walked into the next drugstore, took out the money and subsequently dumped the remains into a shelf. The owner of the drugstore telephoned American Express and was given my telephone number. She called, asked for the address and has kindly posted the wallet and content to me.
I had all the credit cards blocked of course, so I'll be getting new ones. But at least I'll save the expense and hassle of getting a new ID card and Bahncard.
