I bet, I can only imagine it must still feel like a dream. Thanks for posting the serial number of the book. We're so happy for you and your wife Adam, and it is so cool to have it be someone who has been devoting so much time and money playing this game instead of a random tourist. Honestly, knowing that a top prize actually existed gives everyone hope. =p
On another note, if this helps anyone playing $10 Holiday Gifts...
I purchased some tickets in Jacksonville Arlington last week with a serial code of 1292-0112951-9-56, and 1292-0084155-9-023037. The distribution numbers I've found tend to be in the later range, but I'm sure it is certainly possible to find some prior to 60,000. There are still quite a few food stores that have the $10 Holiday Gifts ticket, particularly "Bryant's Food Store" downtown toward the Matthew's Bridge. I haven't played any there in about a week, but I know that game runs really slow and that store loves to stock books of that game.
Maybe the Jacksonville District office has $10 Holiday Gifts with a distribution number less than 60,000? Someone recently found a $1 million dollar prize while enroute cashing in two $1000 winners. It wouldn't surprise me if the last Holiday Gifts ticket were also at a district office, especially considering the large number of books the Jacksonville office still has.
Edit: I double checked my big pile of losers, and I believe I found some Holiday Tickets in the 20k, and 50k distribution number. If my memory serves me correctly, those tickets came from the Jax district office.
