In Mark's 1999 book, 239 chips are listed as:
The city directories for the 2 years before show no address and the year and two years after show vacant for that address. With scan of City Directory.

In his 2007 book listed as:
No Club Location.

His 2013 email to me said:
And so far only the black chips have turned up no red or yellow have surfaced (Yet)
IDed from Raid pictures in 2013-City Bar and Nightclub.

Pretty sure I have all the illegal books written.

No sure where the 239 Club came from or same address as 86 Club.
