Thanks for all the advice everyone. Though the consensus is to keep them, the answer to my main question of the valuation has got me on the side of selling. I'll be on the lookout for a replacement micro cash set so I'm open to trades + cash. I'm leaning towards CC Pharaohs provided I can be assured they won't be chipping on me. I'm in no rush to sell these bad boys, in fact I'm hoping to get into action a couple more times before I part ways.
