That one was very unusual. the case was rarer and it was chrome, never seen one of them as good before. Not worth that kind of money but then again in collectors is some paint splashed by a one eared guy with mental health issues worth more than the national dept of some countries?
No it never is, all you need is two people with deep pockets wanting it. Being on the receiving end when I sold an Aristocrat I cannot say I was thinking "now stop it, it is not worth that much".
I am sure both the buyer and seller are very happy.
