Sorry, but know very little about the chips in general, dates, history, why/when the different materials were issued, etc. Knew once but my old brain with low capacity probably killed those memories to be able to add some newer ones......

Will tell you that most of the chips you showed come from Casinos as they have casino names, letters or numbers. Some with design and no denomination, could be private or used as roulettes. Those I am not sure.

Sorry cannot be more helpful here.
