Around 100 billion caps in liquid assets and 250 billion in illiquid assets. The illiquid assets comes from the takeover (hostile) of the Lucky 38 after the demise of Mr. House. Other illiquid assets include holding a 75% ownership through stock in the Gun Runners. Because of all this, my philanthropy is to clean up the lesser areas around Vegas and personally beating up on the legion. There was an elaborate wedding of me (the courier) to Sarah Weintraub attended by NCR brass, BOS, Boomers, Kings, Followers of the Apocalypse, and many more. The White Glove Society provided the catering and the Kings provided me with a bachelor party. Unfortunately, Sarah insisted on getting married (and living) in Vault 21. I really did not want to, but hey, the things you'll do for love right? We have one son named Ulysses.
Truth be told, I am bankrupt. OWB sent my account from 150,000 to 5,000 on massive ammo expenditure, frequent weapon repairs, and predominantly getting screwed over by the Sink (it did not pay me for my wares past a point).
