Thanks to Johnny, my 1991 set is finished!
I've already cruised through the 1980s. If you're building your own set of Diamond Kings, I have lots of extras laying around.
Here's a want list of Diamond Kings I still need:
1984: Checklist (I bought the whole set, but it had the 1983 checklist in it... Bummer)
1990: 12, 19, and 23
1992: 1, 3, 19, 22, 26
And then it gets really dicey. Just a few in each year.... None so far in 2015... If you have Diamond Kings from 1993 or later, I'm looking to add. If you want Diamond Kings from 1982-1993, I have several to trade!
