I didn't notice the part about 3 different sellers, that does not seem believable. However, I believe it happened to me, one book , old 1st generation label. When I got the slab the case literally opened in my hands. The inner well was sealed but in looking at the book, the label said 9.6 but the book was not a 9.6 . The label on these old cases slide right out of the inner well, making it easy to switch the labels. I love to buy old label books and have cracked open many of them. They can be opened up very clean, little to no damage. The posts can often be popped right back, though they will be very loose and open up easy. Using a snug mylar bag will hold the case together. As mentioned, the new cases are not easy to open.
