70? If it's a 70, I'd do PCGS Walkthrough grading tomorrow in Newport Beach. The Very First In Hand PCGS 70 would bring ~$2K in a 24 hour auction. That's what I did with my early arriving UHR in 2009. One of the first in hand, graded 70 = nice premium. Buy another one for $500 unopened box, and pocket ~$1300 (-cost and grading).
When another poster said there's offers out there to it $500 and more, it would be tempting for sure. I roll probably just keep it.
