I am sort of out of my league here but will give a novice answer. Maybe someone else can help more. I would say that generally earlier baseball related items like these will be worth more UNLESS the year of the later certificate has some importance. A championship, lots of HOF'ers, first year in league, pictures of players etc...could be things that would increase values of later items over earlier ones. Also, if one or the other is way more scarce, that could lead to a higher value. So, in general, all things being equal, I will pay more for earlier baseball items. Hope this helps a little bit.....sorry if I am off base (note all of the puns), I am just going by my limited experience in such items.
