The lesser rings were forged by the elves as essays in the craft of ring making. These rings were made sometime between S.A. 1200, when Sauron came in disguise to Eregion, and 1500, when they began crafting the greater Rings of Power.
Gandalf mentioned these rings to Frodo when recounting the origins of the Rings of Power. Supposedly also did the messenger of Sauron, who asked Dáin Ironfoot to find and return to Sauron "a little ring, the least of rings", that is, the ring of Bilbo Baggins.
