If you have a local coin shop you can ask if the have any slick coins sometimes they'll let them go for cheap
With silver going up to $30/ounce, I don't know if 'cheap' is the word. They'll generally sell slicks (or 'junk silver' it's often called) for the melt value of the silver.
If you're just starting, why not go with Ikes until you're sure you want to blow $100 or more on nice props? Or clad Kennedy halves? Both of these can be found for face value.
Just a side note, if you want more comprehensive information you might want to check out the Magic Cafe, a lot of the folks there have a lot of performing experience, so they can definitely tell you what you want to know.
Most people here don't do coin magic so probably won't have as much information to give you.
I will tell you that if you choose to get silver coins whether they be soft or silver, remember, if you want to get matching gaffs for them, it's gonna cost a hell of a lot more than the alternative, which is clad halves/ikes.
I personally worked with liberties until recently when I switched back to clad kennedy's to work with gaffs.
Thanks but one question....what are the gaffed coins
i'm in france and i found mine on ebayHey guys
Im just getting into coin magic and wondering where to get soft coins and what kind. And since Im only 14 Im on a budget so I can't spend too much
