If one tried to put a realistic price on gold in the 1970s, one would have a difficult task. $35 was a rigid useless number from fdr days I believe.
Based on hazy historical recollection and casual chart viewing, I could go with $200 for gold in 1978. Has inflation gone up 4 1/2 fold in the last 30 years?
A cheap new car then was maybe $4000.
I would argue gold is within a fair current range.
