As Holland Casino are the ones who issuing GO chips & jetons for a long time already I tried to scan some of the older ones too.
First one is an 'older' one, difficult to scan as it has a lot of reflection in the scanner (I need to get myself a digital camera, any advice on model email me pls).
It is from Holland Casino Amsterdam when it opened on 1 December 1986 almost 15 years ago !!
Also they had the 'old' logo

The next one is from Holland Casino Nijmegen, a bit more easy to scan. Grand Opening was 11 August 1989. Still the old logo.

A more recent on from Holland Casino Rotterdam, this when they moved to their new location at the 'Plaza'. Grand Opening was 13 June 1992, with the new logo.

For your vieuwing pleasure, sorry no dupes.
Went to Holland Casino Eindhoven and found almost a full Clemens Briels set, just 1 more. Have to go back next week.
Kind regards,
