With much thanks to Wrigley Wax, I found out yesterday that Donruss did make Diamond Kings from 1992 until 2002. They were no longer part of the base set of cards, but now made as inserts. Here are the Mariners versions of the Diamond Kings for them.
If anyone has any of these, I'm open to a trade for any of them.
1992 Randy Johnson
1993 Ken Griffey Jr.
1994 Ken Griffey Jr.
1995 Ken Griffey Jr.
1996 Edgar Martinez
1997 Ken Griffey Jr.
1998 Randy Johnson
Can I just say, this has got to be one of the most scariest looking cards I've ever seen.
1998 Alex Rodriguez
1998 Ken Griffey Jr.
2001 Alex Rodriguez Retro 2000
2001 Ken Griffey Jr. Retro 1999
Trades are welcome for any of these. Also I'm always looking for cards to finish the Super Set.
Again, I want to give a shout out to Wrigley Wax for the heads up on these. If you want a good read on cards, and Cubs in particular give him a read.
