Have been trying to categorize my childhood binder (circa 1999 ~ 2001) and recently learned that there is a "no symbol" error, but also it seems there are early cards (the "base set"?) that do not have any symbol on purpose?
Is it possible to tell the difference between them based on their numbering? The cards in the first image are all number 1 through 21 out of 102, while the cards in the second image seem to be from a different series, being number 4, 6, 12 and 16 out of 64.
Are the second image's cards maybe all symbol errors? Maybe supposed to be Jungle cards?
