How Rare is an Original The Silver Eyes Cover?

Original post got taken down for some reason, despite it literally being a question due to me being unsure. I happen to have an original run cover of the Silver Eyes, and in decent condition too. I've looked everywhere to find these now, and haven't seen either a post about one in at minimum of 5 years or at all even. I can't even find them being resold! Does anyone happen to know what happened to these, and how rare are they now?

Minor separation on the edge, however no damage is actually on the book itself.
