... usually, documentation of some sort (recordings, video, pictures... something that everyone could see, hear, read, touch, smell, understand and believe). But, you are also right in regards that, even if it is in a book or guide, how do you really know it is true or factual?! Aren't they always rewriting books anyway?!

As for your experience in the casino and the chip you played with and kept, all you have is your word. Maybe it is a counterfeit, maybe not... maybe it was a re-issue chip for that casino, maybe not... maybe it was an error chip, maybe not... maybe it was a reproduction, replica or commemorative chip made by a legitimate chip manufacturer, or maybe not... who really knows, right?! If I was playing at the casino using the chip in question, I would have asked the dealer or the casino pit boss about why it was different. Case in point... your story also happened to me, somewhat. At the Golden Nugget, Las Vegas, I had a $5 chip that looked somewhat peculiar to me (color was off on the chip and the inserts, but the mold, casino name font was similiar to the rest of my chips). I asked the dealer between hands about it, he didn't know. The poker room manager came over, looked at it, walked away with it and simply gave me a replacement chip. Nothing else was said. When I was done playing and asked the poker room manager about the chip, he said "it appeared defective".

In the end, proof or fact is what you make of it, but most will want some kind of documentation.
