Well, weirdness is highly subjective, so your personal mileage might vary.
Historically, decapitated people are a lot more common than are sentient coins – because incidence for the latter is pretty much at zero. Decapitated people who remain capable of acting are a different matter, of course. If we dismiss reports of German pirate Klaus Störtebeker’s post-decapitation antics as mere legend (as we likely should), incidence for this is pretty much zero, as well. Which, however, would only make both things about the same level of weirdness – so Snuka’s judgement would still be subjective.
An argument could be made that the re-animation of a decapitated body is less weird than an anthropomorphic coin by virtue of the body having been originally capable of animation – so it would only be a miraculous restoration of an ability, not a new and inexplicable creation. I mean, coins don’t even have internal organs. Normally. Under this consideration, the reanimated body would be less weird than the coin…on the other hand, the anthropomorphic coins at least doesn’t splatter blood all around it on an ongoing basis.
At the end of the day, there’s no real answer. Snuka is probably just naturally more favorably inclined to the weirdness of an anthropomorphic coin because he’s always had those erotic dreams about money. ._.
More on Monday.
