To transfer an item you just change the owner, you dont need ITC's
if each coin is an item, you just re assign X rows to the new player, if each item is an array of ids where each item name has one row, then just adjust from there for both people, removing the specific amount from the array of the giver, adding that to the array of the taker.
As i said before, if you can split them up into discrete numbers where each one never loses its homeland or ID, you can re assign them properly.
