How many rings did Sauron make?

Sauron (Sala Baker) directly made only one of the 20 rings, the famed "one ring to rule them all," although he assisted in the creation of the nine rings for mortal men and the seven rings for the dwarves. The three rings for the elven-kings were forged alone by Celebrimbor, with knowledge obtained from Sauron. "Three Rings for the Elven-kings under the sky, Seven for the Dwarf-lords in their halls of stone, Nine for Mortal Men doomed to die, One for the Dark Lord on his dark throne, In the land of Mordor where the shadows lie. One Ring to rule them all, One Ring to find them, One Ring to bring them all, and in the darkness bind them, In the land of Mordor where the shadows lie."
