FORGED CRANK........HOW MUCH SHOULD I PAY

A nice original steel forged crank is worth a good deal to some if you want it. I bought one 2 years ago ,original 340 steel crank and was fresh from machine shop , for around $350 , but its what I was wanting so I paid up for something I wanted , and compared to a new price and China steel product its was worth it to me, ,With an original ,between family or friends and your for sure its a good crank $200 would not be a bad price , of course that depends on how close the family and what he thinks it is worth ?
