Been used by Chan. **notice the symbol** they are very similar.

In one of the newspaper articles it says he operated his clubs under the Wai Yeun Social Club

This chip is confirmed sent to his house

These chips Seem to be the same. Maybe there should only be 1 listing?
** funny how someone translated this to "Gather/Send Money to Country and he gets busted for shipping back home to China**

This chip also incorporates the same symbol ( on top)

This chip sent to same address( his home) in Oakland, Ca

There is no guarantee that any or all of the chips pictured above were used in any/all of his establishments. Some are confirmed to belong to Chan, while others are going to be a best guess. One article says he operated any many as 11 gambling operations.
There is so much more history on Bok Hing Chan...most things may never be known, but as info is found out it will be introduced into the hobby.
