Did you know that piano keys used to come in a set of 85 but since the late 1800s, 88 keys became the norm. And practically all pianos made today have plastic key coverings for both the naturals (white keys) and the sharps (black keys). Formerly the naturals (white keys) were of ivory, the importation of which is now prohibited because it requires the killing of elephants for their tusks. It has not been used to make the naturals (white keys) since about the 1950's. Now piano manufacturer uses plastic for the key tops (piano keys) as plastic are very durable, require much less maintenance and are always available.
Sharps (black keys) used to be made of ebony wood; the plastic sharps used today may be shiny or of a slightly dulled appearance. Professional pianist would recommend the dulled sharps (black keys) which are often standard on the better pianos because fingers seem to slip off the shiny ones more easily.
Till today, most pianist still very much preferred Ivory keys because it absorbs sweat from the fingers and doesn't get slippery like plastic does. It is also said to have a "warmer" or "softer" feel to it. Therefore, there are several piano manufacturers have developed synthetic materials that mimic the properties of ivory which referred to as "Ivorine".

Just because the keys are yellowed or discolored doesn't mean they are ivory. Ivory key tops are always made from three pieces per key, two pieces on the key top and one on the key front. There is a distinct grain, much like the grain of wood, and sometimes it can only be seen under good lighting.
