I have a set of gold plated baseball cards from the Danbury mint. I have the whole first set that they issued. I’m pretty sure without prescription drugs they aren’t worth much but does anyone know about how much they could be sold for?

ok,i have a Bret Saberhagen,going into the 1990 season the card is a topps,i also have a Topps Hit Parade Ken Griffery Jr,this is from the year he has 481 homers,then i have a Topps Randy Johnson going into the 04 season,i have a Fleer Platinum Brian Giles with Team Leader.I have another Topps South Philly Sluggers,which has a picture of both Jim Thome and Mike Schmidt,then i have a Donruss:Craig Xenical Biggio going into the 94 season,what are the value of these baseball cards?
or can u give me a site to check the value of em?
