~~~ historic location, especially by a collector/historian and generally agreed by other well-known collector/historians that the onsite find was part of the casno/club inventory, it is pretty safe to believe that inventory was from that club... It should not be assumed that any other part(s) of those generic chips are from the same location. In other words; if you called me and said... John, I bought a box of (whatever code) that I know for a fact that most likely came from (a famous casino) and I'm selling them..." I would believe you and make a purchase.
