The quality of the printing job match fairly well so I can assume the first picture was indeed the CoA for the coin. These were done with a home printer and signed off "Bruce Wayne".
Bruce Wayne was a name - or pseudonym - he used that predates his time on this forum. I remember finding some of his work that he'd tried to sell elsewhere under that name.
Regarding the YouTube video I did watch it back then without realizing the importance it would mean to me now. I do remember thinking that it didn't prove or disprove anything and I just disregarded it at the time. I believe he took it down himself for his own safety. It was brought to my attention some time in 2018 / 2019 when I was purchasing the wooden
Scam Busted piece that there was a crackteam of forum members tracking WoodCollector through all the public information he was posting and everything else they could gather. I saw pictures of his supposed house and was given other links to very personal information. Along with the Culture Cultivation piece and the CoA I posted earlier I received the full packing slip dox of WoodCollector. The member that sent it had made it public but I asked him to take it down, though this wasn't the first time I had seen the same dox. I decided against my own investigation into the name on the packing slip but one day I probably will be bored and see what I can find.
To be honest to me it was more proof that he couldn't do what he was claiming. As far as I recall the intricate design was already done and it just showed him butchering the coin with a hand tool. A lot of people called him out on it so that's probably another reason he took the video down. I'm surprised he posted it at all for numerous reasons really.
