Sorry guys, I forgot to post photos.  My home is overflowing with collectibles, toys, and games, from thrift shopping and I spent most of last night organizing.  Not even close to done, but the journey is half the fun. 
 
To be honest I only paid $25 for the box, so even at $300 value, that's a huge score.  I found it at a garage sale of a flea market vendor who lives next door to a buddy of mine.  He had a full box of garbage pail kids pins and and a full box of garbage pail kids poster cards (unopened) but I felt he was asking too much.  He wanted $80 for the pins, and $50 for the poster cards.  They were from 1986 as well.  I knew the cheap toys had to be something special though. 
 
Thanks for the rarity guide!
