From what I read in a book this may be a jagged clipped edge, the picture in the book was different but the explanation of what it is sounds like this coin any help will be appreciated.

On a copper planchet it would be. But this is a zinc cent. There was a break in the plating and now the zinc is breaking down fast. Just a damaged coin. Spend it before it is gone.

It doesn't look like the missing edge has any copper plating. I suspect this is just zinc rot. I've seen coins with zinc rot so bad it has holes in them.
Edit: coop is faster than I am.

Post mint flan failure, aided by corrosion.
There MAY have been a slight clip denuding the copper plating at this location; impossible to prove that now.
Post Mint damage could have just as easily removed the plating at this location, to allow for subsequent corrosion of the zinc core.
A similar situation can happen with ancient Roman fouree denarii; can be diagnostic for these.

I have seen the pennies with the holes in them,so is there something at the mint that causes this zinc rot?

The copper plating around the area has like a lamination peel look it is kinda flaky I hope I am describing it right and the black part is lumpy,on any of the pennies I have seen in the past with the zinc rot holes they are mostly on other areas of the coin that is why this one confused me and how big of an area that was affected.

Coop I went to your site and watched some of your videos they are real good,how rare is a double clip and how rare is a triple die clash.and it is great that people like you are taking the time to show and explain these different type errors.

I would think the number of clips would make an incomplete harder to find with more of them.
Kevin: I'm glad you enjoyed the presentations. I like the first song on the last link the best. I call it rainy day blues.
On this coin, it someone added acid to it, you would have a just the plating left quickly. The reason they zinc breaks down is the air that gets to the zinc. It breaks down when it the zinc is exposed.

Hello. Very interesting topic. I had no idea that zinc would start deteriorating once exposed to oxygen. That answers a bunch of questions I had been thinking about. Thanks coop. Good posts. J
