Read the QUOTING section of the bash manual page.  It says, in part:

.PP   
A double-quoted string preceded by a dollar sign (\fB$\fP) will cause
the string to be translated according to the current locale.
If the current locale is \fBC\fP or \fBPOSIX\fP, the dollar sign
is ignored.
If the string is translated and replaced, the replacement is
double-quoted.

This is also covered in item 1 in the COMPAT file.
