Seems like an old thread that is still going, but just my input. I actually played a game with these, a local low stakes weekly game switched up his theme to be pirate (I don't know if he's into pirate or did it just because of these chips) and moved venues to his apartment. Small .25/.50 game.
Anyway, showed up and he had these out. I honestly thought it would be cool at first, even if it is not my preference. It just ended up being annoying.
I play with non-denom chips all the time, and never have an issue. But with these I just would lose track. Some look too similar, the values are hard to be logical, and reaching for a stack was just odd. I figured that would be an issue and we just get used to it, I was mostly hoping the sound would make it "fun." Ultimately, while loud, didn't give any sort of satisfaction when raking in a pot or making a bet. Didn't feel like we were actually playing with coins and doubloons, I think they'd need to be smaller.
Just get chips. Even abs chips have a more satisfying sound, to me.
