Another one valued way up there that was opened recently was a 2003-04 basketball Exquisite Collection which I think had a Lebron James Jersey auto rookie numbered to 99. The seller had bought a three-pack case, and was opening them one at a time.

For those that aren't aware of modern box prices, Topps does a product annually called Transcendant that costs about $30K, and includes a whole bunch of HOF autos, a cut signature of a legend, and a ticket to go to a player meet and greet.
