I have the German version of the game so the card may be named differently in the original or might not exist at all. The card "Versicherungsvertreter" says under "bad things" that you lose items worth at least 1000 gold. If you don't have that much then you lose everything.
What does it mean by "lose everything"?
- Lose all your items carried and still in your hand
- Lose all your items and your entire hand
- Lose every card in your possession
- Lose every card and all your levels
