Yes, all of Arthur's valubles in his satchl transfer over. This includes gold bars, nuggets, loot, etc. All of the cash is lost. You lose consumables like plants, cookable meat, cooked meat, tonics, etc. I had custom outfits that they showed transferred, but when I tried to use them, they all loaded as Johns standard outfit. I had to rebuild them. All purchased, stolen, found, crafted clothes transferred. You don't get everything back right away. You have to go through the epilogues.
