I now make it a habit to travel with a pocket full of quarters (oh, about $10 worth) and misc bills, and put an extra pair of cotton/sport socks in the outside pocket of my carry-on. Not much, but "plausible deniability". And when you get to your destination, just put the coins in the sock...
At the very least, you've got a pocket of throwing coins. Ever been hit by a thrown quarter, even through clothes? It stings and leaves a nice welt!
