1799 ½ Penny, is it supposed to look this way? [solved, thank you!]

I took some photos of coins today and noticed the edge of this one is really weird:

Is the edge supposed to look that way?

Also I noticed some verdigris :'( any way to fix that without ruining the coin?

By the way how would you grade this coin?

It's right but that's a rim bump, all the other details are good but I would say because of the bump its F

Yeah that bump is a shame really, but what about the weird pattern on the edge is that how it's supposed to be?

Yeah I think its a security edge mines exactly the same I will check tomorrow to confirm :)

Mine looks similar too I think,

Yes, that is supposed to be there.
