Go to the bank and change your gold from gold to platinum coins.
Say hi

(number of platinum coins you want) <100 gold coins = 1 platinum coin>

All you must do is put your money in a bag and trade the whole bag! Presto! you have traded over 100GP but it is a good idea to change your coins to platnum coins.

You can't change gold into plats at Rookguard.
BUT, you can sell 4 hatchets at 1 time and get 1 plat :D
