Daff here, and I'm going to give you the real scoop on this Henry Evan's product. 

I'll come right out and say it. I don't recommend you buy it. Here's the reason why. The "quarter" that is fused into the dollar looks like a sticker. Granted, the spectator can feel with their fingers and see that it is not a sticker, but what's the point? Would it have been that much harder for Henry to use a REALISTIC picture of a quarter? After all, even though you have apparently  just sent a real quarter into the twilight zone and made it fuse with the dollar, it's still logical that it should retain the appearance of an actual quarter. 

As it is, it changes it's appearance into what looks like a sticker. And that's just plain dumb.

I'm sorry, I can't recommend this, at least not until Henry pays attention to details and comes out with a realistic looking version.
THEN, and only then, it will be a killer effect.
