Prototype Transformers are the rarest pieces that you can ever come across. These pieces were never open to the public, and were used in the creation of the toys. Prototypes can refer to a piece that is the original sculpt, the original first working model (Hardcopy), to the first toy that comes out of the molds. These pieces can be one of a kind, or a dozen may exist. There are many forms, and many variations.
    The most desired of all Prototypes are ones that never got past the prototype stage, and were never released to the public. These unproduced pieces are by far the holy grails of Transformer Collecting. These pieces are usually a suprise, because we don't know what was unproduced until a concept prototype is shown to us.
