A nem is only worth what someone is willing to pay. Mostly color and markings make them more attractive. I paid $250 for it months ago. Just looking to get back some of what I spent. To go further in answer of your question some of the really expensive nems have direct lineage to a specific one. For instance a Cc Supernova is now up to $2000 or better for that anemone.
Thanks to marklugo23 and Relz for the affirmation and bump. My iPhone not really capturing the true beauty of this nem. I?ll try for some better pics later.
