I don't see many for sale but I would say $250-300, maybe more. They can be converted to a 6 valence with some welding so they are pretty desirable.
Thanks, Mark.
You are correct that they don't come up for sale very often. A search brought up a thread where pricing was discussed. Back in 2010 or so, Pat Garvey valued them at $1000+ (restored) while Cairo posted one for $650 (I think it had been restored) and it sold for somewhere in the $500 range.
Like anything, they are worth whatever someone will pay
