It looked like an unlikely place to find any treasures, but in the first room I saw a 1996 Clinton Cola perched on a shelf.
One other detail is the can was still full. Many people will leave cans full thinking it increases their value. The only benefit from buying a full can is I get to choose how to drain it. So when I got home I nailed a couple of small holes on the bottom and watched the 18 year old soda run into the sink. Of course I was tempted to taste it... but I didn't. The cost of Pepto-Bismol and TUMS would have negated the $.20 I saved.
