Mute cancel

A mute cancel is one that has no distinctive features and has no letter(s) or numbering to indicate the place of origin. For US stamps, this could often be a target, double oval, or a circle or lozenge of bars. This killer could be part of a duplex cancel but without the CDS portion of that overall cancel on a stamp, it is often impossible to say from where a stamp originated.
