>condition
Anything other than near mint or mint is trash
>First edition
big bucks if it is, average if not first edition
>Set
If its base set your looking at good cash, (no mark on the right side of the pic, not like OP pic) anything else is basically trash
>If Base Set
shadowless is big bucks (no shadow under yellow border of picture)
So basically good condition, base set, first edition, shadowless charizards go for the most. Base sets and good conditions go for a lot, but anything less than those should go for 5 to 10 bucks
