FFI, II, IIIj, IV, and V have no depictions of GP or Gil. Unsure about the remakes.
FFVI has GP Rain.
FFVII has Spare Change/Law.
Not sure about FFVIII, that one escapes my memory.
FFIX has (surprisingly enough) no depictions.
FFX has Spare Change and Bribe.
Haven't played FFXI, XII, or XIII, nor any of the spinoffs.

Kingdom Hearts has the orbs of gold/purple/blue, but that's not GP, that's Munny.
