On the trade pages they seem to sell for around 1500 CTP and Melters for 2k.
But these are HORRIBLE prices in relation to the things they accomplish in regards to increase in planet stats and size on top of the fact that they are limited on a per player basis.
Personal suggestion at minimum for a person looking to sell them would be at least 3k on any of the +1 size +2 production artifacts. As for Melters my suggestion would be at minimum 5k ctp. The Hydroshifter from the Octafari chain though(+1 size +1 production) maybe 1k just because of an absolute lack of people interested.
