What's the oldest set you have ever found in an ordinary toy shop/store? So Bricklink, eBay, etc. do not count!
What I'm interested in: When was the old set you found released? What set was it? And in what year did you find/buy it?
I'm just curious to find out whether some people still find sets from the 80s or 90s - or sets that are even older than that - in toy shops. Feel free to mention sets that were produced after the 90s! My question is: Is it still possible to coincidentally find any precious gems in such shops or not?
I can just remember buying a Santa Fe waggon 10022 quite a while after it went out of production. However, I cannot remember the year when I bought it. I just know that prices for one copy of that waggon went up like crazy on eBay. And I got that waggon in a toy shop for the price it was originally sold.
