Can anyone identify these coins? Was given to me by my father

Hi everyone,

I have just purchased a proof set as a christmas present for my son.

Upon its arrival I noticed what appears to be damage to the outside of the display case, which is plastic. It looks as if its been levered open but maybe its just cast marks from manufacture?

The coins inside do seem to have slight dust on them and one portrait of charles has a streak of something and another has a dot. I cant tell if they are damaged or if its something else.

The copper coins also have odd toning. A band of darker colour surrounds the coin but only on the non portrait side.

The above could be entirely normal, but as someone who has never bought coins before, I am not sure. I didnt want to bother the seller over nothing.

Can anyone help me?

Thanks

The Queen Elizabeth ll sets were a limited edition only 500 of each book being produced.

It's a 2025 rather than a 2023 but I'm still over the moon with this. My very wonderful boyfriend presented me with it today <3

My short search gave me nothing so I thought I'd ask the peeps here ✌️

Was given these and I don’t know a whole lot about grading, would these fall under ‘ef’ or ‘au’? I get the impression that they’ve been cleaned somehow but there aren’t any areas of residual dirt so I’m not sure.
Also interested in what these might fetch if I decide to let them go. Thanks.
