Over sized cards are a card doctor's playground. That is why they are becoming less frequently seen. Many friends and I have discussed this phenomenon, even as recently as yesterday
. Personally, I love all over sized cards because they are ones that are less likely messed with. Certain caramel issues almost always have the top or bottom bigger than the other....and I mean quite a bit. If you see an E101 or E102 with both top and bottom borders that are small, I would be very skeptical. As for T206's, I will defer to others that have collected them forever. Same thing though, as far as over sized ones, no doubt there are fewer and fewer as time goes by. regards
