It's awesome to see how well these cards appreciated in value. Dug out my collection a few days ago. Sitting on 50 base 5 silver 2 black and a handful of minis. I guess I'll send that couple to HGA while waiting on BGS to allow submissions again. 
Those are good cards to have.. Hotbox silver especially. i would wait for PSA if you are sure they will grade well. Maybe send in through a card shop for best rate.
