I can't say with certainty that they'll become very valuable - who can, really? But what I can say is that this deck is a modified reprinting of the S&M v3 Smoke, that it was part of the S&M v7 boxed set (both of which you already know) and that the design was very disappointing to people who had already seen the previous S&M decks because they switched from their distinctive stylized faces to USPC standard. Additionally, the handling is pretty darn good - most custom USPC decks are since Magic Finish became the default for custom decks last year.
I got a box of these the same way you did. I opened them, and I use them. I wouldn't count on the value increasing greatly, but they sure do work very nicely. As a beginning flourisher, I think you'd be pleased with the performance.
