When Setzer or Gogo uses GP Rain: the three discs that he throws are pictures of GP, not Gil; but they are both essentially the same.Originally Posted by Evastio
Wallets probably aren't a big commodity in the FF world, so they seem to have a small hole in the center. This could mean that a character could hold gil on a string and carry it around in a pocket or something, assuming that it is extremely light, and very thin. There could also be the possibility of gil pieces that are sold or combined together to make higher value pieces, therefore, possibly changing the number on them, if it has one. The markings (lines on the GP) could also indicate its value, by length, or color, or w/e. Unfortunately, the GP thrown in FFVI is generic.
In FFX, however, Bribing often drops many gold pieces, and you can't actually see anyone actually take out the money, you only see them reach to the pocket, and it skips to them presenting the money to the enemy. Also, using Spare Change also only throws many gold pieces, and you don't actually ever see the Gil in detail.
