What is the symbol in the upper left corner of the screen?

Every few minutes during gameplay a symbol flashes in the upper left corner of the screen. To me it looks like nothing more than two grey rounded shapes in a black square, sometimes with the number 2 or 3 at the corner of the square. What does this symbol mean?

edit: I figured it out. It is the inventory icon for money, which the game drips at you constantly at least when playing as the Bachelor for some reason.

Additional info: this icon appears when you found something (most time money) on the street (it's not donated to you char or something). You can find other stuff like needles, clocks or rings.
Mmh, I made more money in 3 days by dealing with trash and stuff I found on the street than Victor Kain seems to own xP
