No worries, I did a few Youtube Videos on it and posted in some comic and Ghostbusters Groups people where generally surprised about it, Ive since noticed a few Ebay Sales since. But I think the moment CGC or Key Collector officially Recognise it, I think they will spike a little.
I sent a massive email to Key Collector explaining it all I never heard anything back but a few days later the listing for the books they already had changed to "First Team Appearance" rather than First Appearance and they added a bunch more Ghostbusters Keys previously not on there. But Eagle comics are strangely not on the system but 2000ad and other British titles from the same publishers are so maybe they are adding them who knows haha.
