The most reasonably priced poker chips available these days in the market are the plastic ones and they are cheap because of the same base and only the stickers and print is different or customized. This is the basic problem with these, as we cannot change the base color and they can be easily copied by any person who is having access of a printer at home or at some other place.
On the other hand, ceramic or clay poker chips are more secured and these are the types that are used in casinos worldwide and clay poker chips are the most antique ones and are in market for over 100 years. Whereas, ceramic are the new ones and several manufacturers are offering these to home players. It is the secured form as the image on a customized ceramic poker chip is fixed within the chip and cannot be removed except we actually break it.
