Imagine taking casino chips home without cashing out, then unfortunately you lose the chip or it gets stolen, it would mean your win was in vain. I personally prefer to cash out immediately after I win. Taking casino chips home makes no sense to me.
Come to think of it, why would I take them home when I can’t use them outside the casino? To motivate me to return and gamble again? That definitely won’t work on me, as I usually have a very busy schedule and won’t go back for any reason if I don’t have the time.
Anyway, I am not a frequent visitor to offline casinos. Maybe those who do this have better reasons for it.
I don't think the OP was thinking of any specific purpose about taking them home, but he was simply curious about what would be the consequences of taking casino chips with you. He did his research and shared it with us. Although I'm not a frequent visitor of offline casinos, I've found the topic very didactic.
I would be interested in taking a few chips with me, for example, if I went to Las Vegas and wanted to keep some as a souvenir. I don't know if I'll go to Nevada anytime soon, but it's good to know that there is no problem with that.
