Test tokens are usually the same size and weight of a coin slated to go into circulation that is different from what is already in circulation because of a change in materials, which may make it lighter than circulation coinage.
The P "mintmark" refers to the new composition of our coins, which are now plated steel. Test tokens made of this metal were sent around to vending machine companies so that they could see what modifications were necessary regarding the proposed changed coinage.
They are not usually dated, and they usually aren't collected in "sets" although they can be collected by type/design.
When testing is concluded on them, they are supposed to be returned to the mint.
