Gold, being more "desirable" can account for some level of deviation, but not to levels like 60-80x.
It used to be around 17-18x when gold and silver were used in coins.
I remember the 5 francs was 25gr silver x 0.9 purity = 4.5pure grams silver per franc.
The 20 franc gold coin was 6.45gr gold x 0.9 purity = 0.29gr gold per franc.
So it was 4.5grams of silver per franc / 0.29grams of gold per franc = around 15.5x... That was in the ~1860s.
So it should be around 20x tops.
I believe the historical average was 12-1 Gold to Silver, but as there is less silver on earth now compared to Gold due to industrial uses never to be recovered, some are calling for a 1-1 ratio when the rigging ends!
They are just silver pumpers. 1-1 will never happen. At best 1-10.
