The June 2018 issue of Science to Sage magazine has come out. Titled, Gold-The Philosophers Stone.
It is full of interesting info on gold but not its financial aspect.
Lots of links for further exploring.
You can buy the issue on line or...for free...go to https://issuu.com/ and do a search for the June 2018 issue.
One can also bulk buy most of the past issues for a very reasonable price.
IMO, the magazine is worth supporting for its ideas, art, quality and the input of various contributors.
