Back in the 70's I spent a summer in Amsterdam and genuinely lost my passport. When I breezed into the consulate a few days later to get a new one, I was horrified to be accused in no uncertain terms of selling my passport. I was 'interrogated' for about a morning and left the building without the replacement I had been depending on to travel forth with my mates. I rang home and my folks made some howling noises to the powers that be and I got a new one afew days later. I later found out that had I sold it as accused I could have got a hundred quid for it. No wonder when a long haired, skint, half stoned and reeking of patchouli scruff, turned up they got suspicious.
