Looks like a genuine clip to me, but it could be post-mint damage. Is the rim opposite the clip slightly weaker? Also, what does the edge look like inside the clipped area? If you can look at it under magnification, can you see the metal flow lines from striking, and if so, do they appear to flow into the gap?
Clips on larger denomination coins tend to be of more interest than small ones, but it's a small, single clip, so it's not moon money or anything. Maybe 5 bucks? Look for similar coins on eBay.
