Sidney Smith is an NPC in RuneScape Classic. She is a certer (like Niles, Miles and Giles in Draynor Village), and exchanges potions for bank noted potions. This was in the days before players could withdraw items from their bank in note form. She resided and worked in Yanille, but was not moved over to RuneScape 2 when it came out, and, unlike Niles, Miles and Giles, who came back in the form of a Random Event, Sidney Smith was never seen again.
