He y'all. I am going through my pokemon card collection and realizing I have some old 1st edition Base Set cards. Ive been trying to find there worth, but having trouble identifying everything. For example, I have a 1st Edition Holo Electode (Jungle Set), and as Ive researched Ive seen 3 different backgrounds it seems, ranging from $5 to $300. What sources can I use to figure out EXACTLY what I have? Im pretty lost. Thanks everyone!
