I am at work and no chip data base to look at. If we are talking about chips put on the tables in a certain year and the same chips are still there mixed with re-orders, I guess the Stardust or Palace Station. Not sure when the Palace Station changed from Bingo Palace, but I can guarentee they are the original chips. Same for Stardust.

If we are talking about original art work and years of re-ordering on Paul-Son chips, I need my database and time to search it. The original chips could have been pitched due to wear.
