Is this a proof?

I know this is not a coin roll find or a metal detector find but I do not know exactly if it is a proof or not. I once bought a 1940 MS-63 nickel but it looked like it had proof features like a cameo I was wondering if it was a proof. It is probably not but it might be. Do you think it is a proof. Here is a picture

The picture is not good enough to say for sure, but it doesn't look like a proof to me.
