Summary: create a series of NPC’s who when interacted with give the player the ability to place items from their inventory for sale, with a corresponding value in gold and silver coins. Simultaneously create a storage system for coins, separate from the inventory with a much higher stacking limit.
Due to the fact that I don’t have any ideas on a way to implement this feature, I hope discussion will assist me in updating this thread.
i added a mod that has extra things in the game, including “scales” a type of coin, and some trade posts. the building looks nice (with 2 tapestry / carpets hanging outside with a list of things for buying and selling), but they dont seem to do anything, and i had to spawn in a coin and a shop using admin features, as they dont seem to appear yet.
but another mod has a Buy and Sell merchant and that is working ok. (just lets you sell like 200 bones for a silver coin or something like that)
