How rare are ARDUN heads?

Steve estimates that 500 sets or fewer have ever been made: the couple of hundred originals, the 30 Don Orosco made and the several hundred made since. When he asked Don Ferguson how many reproduction sets exist, the answer was in the hundreds; the heads are not serialized.
