Nope, just tried the title "$0,120 to $1,200", it worked perfectly fine.

Probably OP used some plugin to post this which is faulty.

Looking back at the user's submissions they posted a link with the title "The" 47 days ago, so this seems likely.

Or maybe it's a bot. Somebody should try to make it post a story with $$ in the title and see if it escapes it to the PID... :-)
