They keep giving coins until there is only like one or two zombies left, and then the output is pathetic. This prevents you from deleting all your shooters and just infinitely repairing tallnuts.
You get 2250 or so just playing mostly normally and building money plants when you can. You can stretch out the length of the round by killing zombies more slowly, and the cloning plant supposedly helps too. I have never really gotten more then 2800 or so gold, but I havent really focused on it since getting the cloning plant.
