As always, click the image below for a trip to a decent but mildly opinianated little piece on the issue.
As an aside,
The last sentence of the above article reads,
"In 1974, President Gerald Ford signed legislation that permitted Americans again to own gold bullion."
It should have been followed by the following,
"And in so doing, realiized a tidy little profit for the federal government of the United States of America."
Not entirely sure what "recover real value" means in the above chart.
Thought about it for a minute.
Decided I just didn't care.
