Here is a video that I made on the Coinage Act of 1792 and the Gold Silver Ratio.
I have heard more than one of the Gold bull's mention that the ratio will go back down under 20. One mentioned that the ratio goes back down to 16/17 to 1 in every secular Gold bull market.
At 1250 Gold and a 16 to 1 ratio, Silver would be at $78 ! At the close last Friday, it is at $18.25. Looks like it has a long way to go to the upside if the ratio were to come down... Keep an eye on the ratio this year.
