What you need to consider with a coin unique, as wonderful as it is, is that it needs a reset after each trick. In most performances this makes it a one trick pony as it's not a reset that can be done in front of an audience.
The same principle generally applies (but not always) to trick decks and tricks that use a gimmick of sort - or modified gear as you refer to it.
It's advisable to buy material that doesn't use or rely on gimmicks when you're starting out. While it generally requires a little more practice to master, the result is nearly always more worthwhile from both your own perspective and that of your audience. Also, the sleight of hand skill that you develop is what ultimately elevates you into a magician as opposed to just being a trickster.
All of the material so far recommended has stood the test of time for the reason that it's good and has been the starting point for just about everyone of note.
My advice is to take the advice already provided in the previous posts.

It's not really an optical illusion - it just looks like one!
