I would like to add sets and checklists for two series of Slamco Marvel Comics pogs released in 1993 and 1994, but I know that pogs are mostly outside the scope of this site, so I wanted to make sure these particular sets are allowed.
Slamco released four series of Marvel-related pogs in '93-'94 -- two series of X-Men and two series of "Marvel Comics," which also featured plenty of X-Men characters. Slamco was not a card company, and their pogs were not packaged with cards, which would lead me to think that these are not allowed to be added.
However I see that sets for the two series of X-Men pogs already exist (created by Admin in 2016), and I also know that PSA will grade them, as they were a licensed product and feature widely collected characters. This leads me to think that adding them is allowable after all. Is this correct?
Thanks
