Some useful info on poker chips...
Poker chips are made in a variety of different materials such as plastic, clay and clay-composite. Clay-composite results in the combination of clay and plastic with a metal insert for weight. They are durable and will not scratch or dent easily. However, clay is very popular on the market for its appearance, feel, durability and price. Indeed, clay poker chips, which are the ones used in most casinos, have a better feel and durability. Clay poker chips have different weights, usually 8.5, 9 or 11.5 grams.
Poker chip sets typically include 300 or 500 chips. Sets of 300 chips are suitable for up to 5 or 6 players and sets of 500 chips are recommended for 7 or more players. Finally, some sets of poker chips include accessories such as a suitcase, card decks, dice and a dealer button.
