The 1997 Donruss Limited is a 200-card base set and was released in the July of that year. One of the most bizarrely structured base sets ever, this chrome-stock set is divided into four unique subsets: Counterparts, Double Team, Star Factor, and Unlimited. This sale is for the "Star Factor Limited Exposure. Printed using what Donruss called "Holographic Poly-Chromium Technology" on both sides, 

Limited Exposure is, for all intents and purposes is similar to the "1994 Topps Finest Refractor" . The backs of each card have the words "Limited Exposure" printed beneath the card number.

Like the base set, the Counterparts are the easiest to find, and Unlimited the toughest. According to Donruss, only 40 copies of each Star Factor Limited Exposure exist -- although they are not serial-numbered

The 1997 Donruss Preferred set was issued in one series totaling 200 cards and distributed in five-card "tins". The set features color player photos on an all-foil, micro-etched card stock. Also similar to 1996 & 1997 Finest, the set is fractured into 100 Bronze, 60 Silver (1:3/packs), 30 Gold (1:12), and 10 Platinum (1:48) cards.

The Precious Metals were randomly inserted in packs, this 25-card set is a partial-parallel. Each card is printed with one-half ounce of real Silver, Gold, or "Platinum" embedded into the card. Only 100 copies of each card were produced. Cards like this are reserved for the true collector so please inquire with any question before purchasing.
