Comic collectors generally go to a grading service like CGC to grade and slab an important comic book. Then there are exceptions like Valiant teaming with CGC to offer grading for the SECRET WEAPONS #1 VALIANT VALIDATED SIGNATURE SERIES (VVSS) edition. The issue features virgin cover art, not nearly as good as extra-virgin cover art, which means it is an unrefined oil and the highest-quality olive oil you can buy. It also comes with a hand-written signature in gold ink from Academy Award-nominated writer Eric Heisserer, and an official VVSS embossed seal.
Valiant is sure to let collectors know that the signed Valiant Certificate of Authenticity included with each copy will not be encased with the graded comic. That was my biggest worry.
The VVSS edition needs to be received by CGC by September 27, 2017 to qualify for the CGC Signature Series certification. Secret Weapons #1 is out June 28.
