Which chips best suit your needs? - Which look the chips should have is purely a matter of taste. The only question here is whether you can use chips with values or chips without values better.
Chips without values are particularly suitable if you want to flexibly assign certain values to the individual chip colours. Reasons for this could be that you want to simplify the conversion to certain amounts of money or, for example, in a tournament where the blinds increase, you want to assign a new higher chip value to chip colours that were previously eliminated.
Chips with values are well suited for beginners and playgroups that do not have any special requirements for chip denomination. The given values simplify the preparation of the game and make it easier for the players to place the desired bet quickly and safely.
