Good evening, I have a couple of DVDs that were autographed back in July 14 2018 at the San Diego Naval Base Exchange by Chris Ayers, Chris Sabat and Sean Schemmel and I'm wonderimg how much each is valued at. A friend of mine is interested in purchasing them and I would like to give him a fair value. the first one is DBZ Battle of Gods DVD and the other is DBZ Season 5 DVD set. I do have pictures and video of the event just have to find them in my pack of external drives.
