I can't stress enough how important it is for this to be implemented, this certainly isn't the first thread made about this.
The items that are discontinued, but still able to be traded and sold about such as Marlins, Sea Blasters, Twisters, Gold/Green Forgottens, and Black Dragon, have people unwilling to sell simply because of the trade system.
You simply cannot trust someone to trade you 4/5 times+ with items or gold enough to get these items.

So many scams and disputes are a result of this limit of 10m gold per character.
Could we please get a response from the Dev team on this?

Also I've seen screen shots of old school PL days having 26m + on one character at a time. So it would seem the trouble here wouldn't be upping the gold on the character, but rather CS where players would end up posting some of these things.
