Unfortunately when Champion sold off their stock of marbles, it included empty polybags and headers. People put the marbles into bags and stapled on the headers. Then, when "they" ran out of Champion marbles, they put a lot of other marbles into the bag. For example, the bottom two pictures have marbles in there that are not Champion. The top bag could very well be Champion marbles but the marble count is way off - 14 instead of 20. Off by one count is somewhat normal but not 6. So, your bags are probably "filled" bags. By the way, they do not really fit into the fantasy bag category because they are real Champion headers. That is why I used the term "filled". This also happened with some advertising bags that Champion made over the years.
