I have a few variations of Beast Wars Optimus Primal and Megatron, both Transmetals. I'm considering selling them but wondering what the general going rate is. I have the purple Optimus Primal (MISB), the bluish purple Optimus Primal (loose), the pink Megatron (MISB) and the light purple Megatron (MISB). I also have the tenth anniversary Optimus Primal and Megatron MISB. These are the molds that were released in Cybertron and came with little models of their respective ships. Any idea what any of these tend to go for?
