Can't tell. Wish they would have photo'd the edge.

looks like an AU coin with a big rim ding. Looks like damage to me but I'm no expert on half cents.

It's not damage, that's a classic "rim clip", happened when they were cutting planchets with a machine resembling a cookie cutter. The cutter just got too close to the previous row and cut a row of planchets with a small piece missing. I don't believe there is much, if any, premium value for such an error unless it is more profound than that one....but a rim clip, mint error, it is.

If you want to know if it is a true planchet clip or not look at the opposite side's rim for often seen weakness (looks like this one does show weakness). This isn't always present though. Usually when the rim is upturned, the clip causes a lot less pressure on the opposite side during the process so the rim is weak. There is a name for this effect but I don't remember offhand.

The curve is too soft to be damage... i vote for clip.

The effect you are looking to name is the "Blakesley effect," which happens in the upset mill when they are up-turning the edges of a blank to make a planchet. Since the diameter of a blank is smaller where the clip is, the opposite side of the planchet from the clip remains flat through the striking of the coin - which usually shows on the finished piece as weakness opposite the clip.

This effect, of course, would only be present on coins in years where the upset mill was used, and I am not sure that is the case with this particular coin.

It is a "clipped" planchet.

They did use a Castaining machine to uspset the edges on the half cent planchets.
