1861 Confederate Half Dollar

There are many reproductions of that coin.

I'm guessing you're talking about the true Confederate Half with the normal-style obverse and Confederate-designed reverse, and will answer with that in mind.

There are only 4 originals, and it's known only 4 were struck. This isn't one of them.

in 1879, J.W. Scott obtained the original Confederate reverse die, ground the reverse design off of 500 actual 1861 Halves, and restruck them with the Confederate reverse. These are quite valuable coins in their own regard. They're characterized by a relatively weak obverse compared to a sharp reverse, and are lighter at ~12.44g as opposed to the normal 13.36g.

In addition, more common fakes abound.
