Strike,

You said, " Gold went from $35 to 887.50 in that bull market, a factor of 25. We started at $252 in this run; $252 times 25 = $6300, "

Wasn't the $35 price set by the US gov't? If so, what would it have been if not controlled?

The first chart shows a relatively gradual triple to $100 over the first 3 years to 1974 - no discontinuity. When DeGaulle demanded gold for dollars in 1971, the US had to delink the $ from POG, hence that price rise. But up to that point, $35 did not cause a run on the dollar.

$6300 is as good a guess as any IMO.
