Wax boxes are easy to manipulate. The wax you bought was probably good stuff (not resealed), but it was searched. Let me explain. Let's say you have 10 wax boxes of 1982 Topps Baseball. You open a box and 7 packs into it you pull a Ripken. You put the other 29 packs aside and move on to the second box. 19 packs into it, you pull a Ripken. You put the other 17 packs aside and move onto the third box. 11 packs into it, you pull a Ripken. You put the other packs 25 packs aside and move onto the fourth box. Well, you get the point. In the end, you have a lot of packs left over that probably do not contain a Ripken. You put those packs back in the empty boxes and wallah, you have 1982 Wax Boxes that have been searched, but not resealed. Then you ship them to Steve Hart for authentication. He authenticates them and wraps the boxes in cellophane with his logo, slaps a hologram and a label on there and sends them back to you. There, you have 1982 wax boxes with Steve Hart's approval. You sell the wax boxes and then some buyer feels all warm and fuzzy about their purchase because it has been authenticated by BBCE.
That's probably what happened to you.
