The UD is a double error Don Baylor card with the Griffey overprint on the back. Card is also missing the hologram.
The Star card has the Durham Bulls Brian Deak overprint on the back. Kinda cool because both cards are #9 The front has at least 2 overprints. One is upside down and the other is a Jose Canseco card the correct direction. Similar cards on eBay are listed as high as $54,000.
