HOW TO DROP GOLD ON AN ESCAPE?

Okay a more simple question this time. For the FFIV remake I'm doing, It would be nice to know how to replicate the 'drop gold' on escape routine. E.g when fleeing a battle (successfully) a random (but not too much) amount of gold is dropped, and a message is displayed.

If there's any existing script or code out there that can do this, please let me know, and I'll give you free cookies :)
