If an item sold by NOVA SPACE was turned down by Zarelli then I personally have my doubts about Mr Zarelli. NOVA SPACE is the very best and most respected authority on Space Collectibles .
Someone on these forums made a harsh comment about these authenticators being licensed.
In many ways, I agree that these authenticators should be accountable. I never noticed the little disclaimer notice on the Zarrelli COAs until someone on this forum mentioned it and I'll be Dammed if it ain't true..it clearly states as follows " ZARRELLI AUTHENTICATION , LLC MAKES NO WARRANTEE OR REPRESENTATION , DOES NOT GUARANTEE AUTHENTICITY AND SHALL HAVE NO LIABILITY WHATSOEVER FOR LOSS OR DAMAGES ALLEGEDLY SUSTAINED AS A RESULT OF THIS OPINION " .
