I see where you're coming from, but I believe the notion of a 'trick coin' is just as obvious... especially with the typical straight-outta-the-package handling that everyone's seen Blaine do on televison. When it all comes down to it, the entire plot is arguably 'too perfect,' but that's a different debate altogether.
I prefer the Belanger for the variety of handlings and restorations it offers. My favorite restoration looks just as good as the traditional gimmick, except it's practically done in the spectator's hands. As the spectator holds one end of the cigarette, I break it in half and the coin falls into their awaiting hand instantly restored. I've also seen handlings where the hole melts away much like the gimmicked coin.
Both items are very good, and they're both classics. I just feel the Belanger is severely underrated for its simplicity.
Have you ever tried Derren Brown's handling for the traditional gimmick? Ballsy.
RS.
