1990 Bowman Tiffany -vs- Base Cards
The Tiffany cards differentiated from the originals by being printed on white cardstock with a high-gloss coating. Many sellers on eBay and other sites, will list their regular cards as Tiffany cards. The easiest way to determine a Tiffany card from a regular issued base card is to look at the back of the card. The Tiffany card backs will have a clean white background, while the regular issued cards will and appear to be gray. It is also important to note that many sellers will attempt to brighten the regular cards to give the appearance of a white background. With current printing technology some sellers have now created their own fake reprint Tiffany cards, which can make it impossible to tell the difference between a real Tiffany card and fake by simply looking at the back. Therefore, once you have the card in hand you will want to check the thickness and gloss of the card by comparing it with another Tiffany card of the same year.
