buried treasure!

I recently purchased a 1999 silver proof complete 9 coin set in ngc proof 69 on ebay "buy it now" for $319. not a bad deal, eh? but it gets better....buried in the description page of the listing, not the title page that most buyers look at, the seller casually mentioned that the whole set was pf 69, except the connecticut quarter which was a proof 70! It's a beauty! So is the rest of the set! As a new collector I was shocked this set and it's buried treasure came into my hands....but I'm not complaining. It just taught me a very good lesson in collecting on ebay, to look just a little closer at each listing and hunt for more buried treasure!
