All of the poker chips are not equal and hence you need to know the difference between plastic, clay, and other kinds of poker chips prior to buying them. There are three types of materials used to create the poker chips which are metal, clay and plastic. Clay poker chips are the fanciest kind and they’re made of a combo of clay and other materials. Poker chips made of a metal core surrounded by plastic are the closest match to what you’ll find in most casinos. Plastic poker chips are a lot cheaper and you can pick them up at toy stores. You need to stock up on different kinds of chips, based on the size and the nature of the game.
