The cards are usually closer to M than NM, but since they are not "pack fresh", as the modern phrase goes, I don't class them like that. When the set was first released, these were put into the folder (or those long cardboard boxes) as part of the set collection when the packs were opened. Some were used, but I played them sleeved.
Some of my cards have sat in folders and sleeves for a very long time. Condition of cards is as seen in photos.
Sorry for the glare, if any. Please ask for more photos if you need closeups. Slowly going through the collection, and will end up offering Common, Uncommon, Rare cards. Mostly older sets at the moment.
I usually go to the Post Office twice a week due to shiftwork. Let me know if you need it in a hurry.
Registered post for single common cards simply do not make sense.
