I consider mould alignment in relation to center inlay on roulettes. I prefer to have the word "roulette" at the 12 o'clock position directly above the center inlay when I have a choice .... such as after harvesting a stack of 20. If someone has a single roulette chip I need, I don't pay too much attention ... unless I am offered duplicates. As to paying a premium for such variances .... No, I do not. However, if I see such a roulette chip with the 12 o'clock alignment offered on ebay ... and if I am the successful bidder, I expect to receive the chip that was illustrated and not a substitute. Just a personal quirk of mine.
