1987 Donruss Barry Bonds
Many of those other same players also appear in the Fleer and Topps releases, but I think that this set has two major advantages over the other releases. First, this set was the of the last dark bordered sets produced by a major card company before the arrival of Upper Deck in 1989. Upper Deck forced the other card companies to elevate the quality by changing their card stock and cutting methods. The cards looked great, but it also eliminated some of the imperfections collectors would run into with older sets. Especially older sets with darker borders. The second reason:
1987 Donruss Greg Maddux
The inclusion of a Greg Maddux rookie. Maddux also appeared in the 1987 Topps Update release, but this card is frequently considered the Gold Standard for his rookie cards. Maddux is a sure fire first ballot Hall of Famer, but he can fly under the radar at times with his baseball cards. This card isn't a hard find and raw copies of the card will only cost collectors a few dollars, but finding one with a high PSA grade will cost you over $50.
Like the 1987 Donruss Set? Not in my Top 50 countdown is the 1985 Donruss set. Similar to the 1987 set, the 85 release is filled with important rookies and also features a dark border that can be condition sensitive. Finding raw copies of the set and singles is not difficult and generally is inexpensive.
1985 Donruss Eric Davis
The Eric Davis cars above is one of his three rookie cards released in 1985, however the stars of the 1985 Donruss set are Roger Clemens and Kirby Puckett. The Clemens card is the better of the two cards, but has been set back in recent years due to the linkage of his career to the use of steroids.

The other important rookie card is the Kirby Puckett rookie. Puckett had his career cut short due to injuries and glaucoma, but was still elected to the Hall of Fame. This is my least favorite of his rookies, but still proudly own a few copies.
