I think it would be better for the players if tokens were an item like they used to be. Pretty sure they were sunflower petal things before, it's just better having them as an item as you can sell them at chest shops or aquire them upon killing someone.
Yeah, I remember this being a thing. My guess is its not an item anymore in case someone finds a way to dupe it. I'm not sure, to be honest.
well it would just be like any other in game item, there's no special way just for duping tokens
