Front-silvered mirror.

A typical household mirror is a sheet of clear glass with the reflective silver coating applied to the back. This means that the reflective surface of the mirror is protected by the layer of glass itself. The drawback to this is you can sometimes see double reflections - light reflected both from the surface of the glass and from the silvered rear surface.

Front silvered mirrors have the silver coating applied to the front. They therefore avoid the problem of double reflections but are extremely vulnerable to damage, as the silvered surface is exposed. Such mirrors are commonly used in SLR cameras.

cf. single lens reflex (SLR).
