I originally acquired 6 chips (a blue and 5 brown). Two browns immediately go, like all chips I find, to two particular collectors. I have, therefore, exactly two brown chips available for trade.

The DBC, according to the seller, is an old New York City club. Chip was sent by the USPC to Mason & Co., Detroit, MI in 1929.

Until further corroboration, I am listing it as unknown.
