Didn't even realise this guy had no price on him, any help? Thanks in advance.

Nuclear Zasaba Beanbag was released a few months ago r92 and is currently ~700K, so thats what its probably going to trend towards. From there it is just a pricing strategy.

If it were me I would price it probably at 20mil and see if it sells. If someone mailed me an offer of 5mil, I would take it. Noone should pay that high of a premium unless they are actively going from the complete achievement, and there are very few of those people around.
