S.P.E.W. badge

A S.P.E.W. badge was a badge made during the 1994–1995 school year by Hermione Granger for the purpose of supporting her newly created society, the Society for the Promotion of Elfish Welfare, which intended to establish certain rights for house-elves.

History
"We start by recruiting members. I thought two Sickles to join - that buys a badge - and the proceeds can fund our leaflet campaign."

- Hermione Granger

Hermione Granger created the badges and presented them to Harry Potter and Ronald Weasley when describing the society to Harry Potter and Ronald Weasley and appointing them secretary and treasurer respectively.

She charged two Sickles for the badges and began a vociferous campaign to get as many people as possible to buy them. Both Harry and Ron bought one to try to keep her quiet, but she instead both badgered them and others to wear them. Some, such as Neville Longbottom, paid simply to stop Hermione from glowering at them. Many, however, regarded the whole society as a joke and refused to buy a badge, including Fred and George Weasley.
