I think any wax product can be judged like this:
1- Not worth opening at any price, burn the money & save space
2- Worth opening later after the price drops
3- Worth opening now, price is liable to increase
4- Worth buying for resale later
I'd say SP Authentic is a strong candidate for the 3rd and 4th category. You can make money on boxes/cases now if you hit well. This does seem to be a typical UD hit-or-miss product, with very little middle ground. If you possess the strength to have it lying around and not open it, it's a great product to buy for resale after the supply dries up. The chane to pull Crosby/Ovechkin/Malkin in the same box/case is too much for collectors to pass up.
