It's not that crazy.
A $1000 bundle of 20's is 50 bills. Usually they're wrapped up like that. That's only 15stacks. You'd only really have to count one of the stacks, if you didn't trust them.

I read the GP as saying 15.3k bills (i.e. £306k), not £15.3k in £20 bills. In which case, that's 306 stacks.
