This is the format of adroc's output from "makepasswd": "$1$" + base64-encoded string (a salt) + "$" + another base64-encoded string (the hashed password). No quotes there.

The source for makepasswd on my system is available here: http://packages.debian.org/lenny/makepasswd. After examining that code, I can't see anything that disagrees with what I said. And this is a standard format, so some other "makepasswd" should produce the same output.
