The reason for so many unlicensed cards not appearing in checklists here is the simple fact that there's no telling what constitutes a checklist for these things.
Are there others in the "set"? Does it consist of other players? Or is there several of just Ryan? How many total cards? When was it made? Are they still being made? Due to the unlicensed nature, not a lot of this info is forthcoming from the makers. In fact, most of the makers of these types of cards were fly-by-night type people who would unlease millions of these cards, state that they were part of some "series", but the rest of the series would somehow never show up. It has nothing to do with rarity or value. In fact, most of these rarely would crack a $5 (more like maybe $1 - $2 each, at most).
