I'm going to dedicate this page to monitor Silver/Gold Premium Charts. You can go to this page by clicking on the favorites link at the top of the page.
I will monitor the silver premiums from First Majestic Silver, APMEX silver coins, APMEX junk silver and Shanghai silver/gold premiums (accessed here).
Even though silver dropped to its low of $18.7/ounce, miners have not dropped prices of silver bullion. The result is a record high premium to get your hands on physical silver.
Junk silver premium is falling.
