I had the various stacks (including alot of necklaces) from the Dungeon and Troll Cave exploring I have done and the Viking graves I dug up. My Island is almost all explored and I am closing in on 100 hours and I have only just found the Swamp (yet to face Bonemass). I like to complete as much as possible before going on to the next "level" so, yeah, I had alot of treasure to sell.

As far as Portals go, I have them (5 of them as all Biomes are connected to my Island as I found in exploring and left at the Biome edges) and have one set up beside Haldor's camp. It still took several trips through it to my home Base to sell everything at first encounter of him and bring the gold home. Caught me by surprise at being "overloaded" and unable to move after selling most of it and had to build a chest next to Haldor's camp to accomplish the task.
