I don't know if I'd set out to go out to look for something specific in mind when I finally got a chance to go to a card show where they sometimes still sell cards - this one vintage dealer with a booth uncharacteristically has some assorted nickel and dime junk to rummage through, so I dug out the following cards from the quarter box.
1967 Topps Wayne Causey #286
1975 Topps Al Hrabosky #122
1990 Leaf Rickey Henderson #160
1994 Bowman's Best Tony Clark #62 - it's probably how the technology in making these cards have aged, but there seems to be some discoloring issues with the foil / refractor surfaces.
1997 Bowman's Best Jamey Wright #181 - as a baseball fan, I find it kind of fascinating how journeymen [85-121, 4.93 ERA] like Wright latch onto MLB jobs towards their mid 30's and possibly through their early 40s.
2000 Topps Traded Chrome Brian Sanches #T64 - he was signed this past offseason to see if he can make the Philadelphia Phillies Opening Day roster.
