[LotR] What happened to the lesser rings?

There are rhymes and stories about the Great Rings, the Rings of Power, but what about the lesser rings? The first ones made in Eregion which according to Gandalf were only "essays in the craft before it was full-grown, and to the Elven-smiths they were but triffles" though many in number.  What could they do? What happened to them?

All of them (great rings and lesser rings) but the 3 fell into saurons hands as he invaded eregion. the 3 were saved, and sauron later gave the rings to beeings he thought easily corruptable (first dwarfes, that did not work out too well, and the 7 he gave them were lost to fire or returned to him, 3 he still has, 4 burned, then men, the 9 he gave them all did what was intended, and made the nazgul), what he did with the lesser rings is not known... some say that the ring of mordor, that gothmog wears, is a lesser ring of power, Saruman and Lurtz both had Rings, too, but it is unclear if Sauron gave some to Saruman to corrupt him, or Saruman succeded in trying to rediscover the art of ringmaking and made them himself... else they are somewhere with sauron, together with the 3 "dwarfen"- Rings he still has.
