I am purchasing a bag of marbles without seeing what's inside. It's a worn plastic Marble King bag ... probably the contents are barely vintage if even that old. And there's no guarantee that the contents are even mostly Marble King. And the condition of the marbles are probably in line with the condition of the bag.
It's a middle-aged man's childhood collection. He's a friend of a friend and I'm buying it for a modest price to be a good sport and to show gratitude to my friend for being on the lookout for marbles for me. And it will be fun to see an intact collection from someone's childhood who is about my age.
After my offer was accepted, I did say that if the bag turned out to have anything rare in it, I would do right by the friend of the friend.
So now I'm fantasizing about what might be in the bag.
