In Christopher Nolan's The Dark Knight, Harvey Dent starts off with a double headed coin, which then gets turned into having two different sides when he becomes Two-face.
Is this the same in the comics?
Is Two-face's coin a regular coin?
In the original Detective Comics #66, after becoming hideously scarred, Two-Face disfigured a two-headed silver dollar with his knife. The coin itself originally belonged to Vincent "The Boss" Maroni and is usually shown as having scratches on the side with either Lady Liberty or, in later serials, Lady Gotham.
This theme is continued in future comic serials such as Nightwing
And the rebooted Detective Comics
