I’ll concede your mastery of the subject, my thoughts being not always reliable remnants from High School history 40 years ago and assorted documentaries on TV.
My main historical interests are mostly of the last several centuries.
Besides,Thule,Atlantis and Mu are much more captivating ancient civilizations than stuffy bloody old Rome;)
Those are pretty interesting places to study, not least because the field is so wide open. :’)

Commodity Numbers FAQs
How much gold is there?
http://www.galmarley.com/framesets/fs_commodity_essentials_faqs.htm
In the world there are currently somewhere between 120,000 and 140,000 tonnes of gold ‘above ground’. To visualise this imagine a single solid gold cube with edges of about 19 metres (about three metres short of the length of a tennis court). That’s all that has ever been produced.
Divided amongst the population of the world there are about 23 grams per person, about 1.2 cubic centimetres each. This equates to about $250 - $350 worth per person on Earth, depending on the current price.
