What are those coins?
When you shoot the guards a lot of coins come out of them ! That's one way you can get more money. No all the guards have the same money and the more you shoot at the same guard the more money you can get.
Where can I get more coins?
No all the money is in the pocket's guard. This is a bank so you can get a lot of more money in the safe but do NOT enter the bank before you have killed all of them except ONE. If you kill all of them you will not be able to open the safe ! If you enter when there are more then one... you are dead.
