And apparently the Bigfoots are just an offshoot hominid, but native to the Mortal World. White Court are Ageless and "Half-born" but not truly Immortal by the definition provided in CD.
Are the White Court even ageless? They could be, but I don't think we've seen any who are older than the oldest wizards. IIRC Lord Raith's portraits go back to 1700 or something & he's the oldest we know.
Even if they are truly ageless, they are definitely not 'immortal' in the CD sense, but I don't think they're even 'non-mortal' in the way Red/Black Court and Fae etc. are. I think they're more like Hexenwolves and Denarians (who are definitely ageless, and definitely still have a human soul) - with both a human soul and a non-human spirit coexisting.
IMO scions, pre-Choice changelings, werewolves (who are basically just a special class of minor talent), loup-garou, hexenwolves, White Court are all eligible for coins - anything with a human soul. But Red/Black Court, full Fae (humans with a Fae Mantle might be a different case - Molly as she is now probably could take a coin), trolls, etc. couldn't.
