1989 Upper Deck Factory sets

[Klrdds]

With the increase in the value of the Ken Griffey Jr rookie card in this set i was wondering about the sealed factory sets. I purchased 4 factory sets from my local card shop in 1989 when they were released and they were sealed with only a round clear cellophane sticker about 1 inch - 1 1/2 inches in diameter 1/2 way along the flap side of the box/set. In fact all the factory sets that I saw for that set were sealed that way at my local card shop and even at other card shops and at card shows as well. I recall being told at a card show by a representative that this seal was extra strong so that if removed part of the box labeling would be removed/torn also so that a buyer would be able to see that the set had been opened. Now I am seeing these sets for sale/auction sealed with a cellophane / plastic "shrink " wrap w/ no round seal mentioned or visible.
Was this factory set sealed in different ways from the factory :
1. with the round cellophane seal only
2. shrink wrapped only
and /or
3. shrink wrapped and with the round cellophane seal ?
Or have these shrink wrapped sets been opened looked at and then re-wrapped ?
Thanks

There are many shrink wrapped factory sealed sets, just have to know what the seam should look like and hoq it runs on the side of the box, and it's thickness. And yes, there are also ones without the cellophane that just have the round plastic seal you describe. PM me if you have more questions about these....
