Wallet, Cellphone, Keys ( You don't say )
Minimum 2 decks ( Usually both with borders and different backs )
A ring
A rubberband
A sharpie
Several coins ( usually in my wallet )
Now this is my everyday, or should I say, Impromptu preparation. Which means, I would never know if suddenly someone just point me with a request to perform. These are the "props" that I would bring everywhere, anywhere, anytime.
If I knew I would do several performing ( either by request or just doing street magic )
I would bring the extra following :
Loops
Tarantula ( well, sometimes )
Ultragaff deck, or any gaff in that case. ( depends on my mood , actually )
Of course, these would be the stuffs I bring for a walk-around magic, not a standing semi-stage street magic.
