@MrAboo I suppose some, if not ALL of those rings are not rings of power. Celebrimbor and Sauron will start to create them not before the end of 1st season imho.
Anyway there were 19+1 rings of power. The most powerful are the 3 for the elves kings, created by Celebrimbor and not corrupted/only partly corrupted by Sauron. 7 for the Dwarves and 9 for the Men (Nazgul), then all alone Sauron created The One Ring to subdue the others. Also if I recall well, there were minor rings, not included in the count of the rings of power.
