Buyers should beware of both loose 1989 Upper Deck Baseball packs as well as unsealed boxes. The most common listing is for loose packs but the occasional unsealed box will show up from time to time. The reason buyers should be leery of these items is quite simple. The 1989 Upper Deck product has a pack/box sequencing pattern that I will not describe here in detail as the information could be used by unscrupulous sellers not yet familiar with the technique. A person familiar with the pattern who has a full box can open a few packs and quickly determine if the box has the coveted Ken Griffey Jr rookie card as well as any other Star Rookie card. Once the person has the Griffey card in hand he can replace the missing packs from another cherry picked box then sell it like new or simply sell the leftover packs. Do not buy a box of 1989 Upper Deck that is not sealed or you risk getting scammed. Definately avoid loose packs of this particular product unless you know a reputable seller.
For the cost of packs you are probably better off flat out buying the Griffey card. The 1989 Upper Deck Griffey card is often found off-center so even if you made the lucky pack hit the card may not be gem mint. You should be able to find a well-centered Griffey in the auction listings in graded or ungraded form.
