1987 S proof set with interesting errors?

So I’m totally new to the entire coin world. I recently acquired a what I like to think is a nice collection of uncirculated sequential bills, a bunch of proof sets, mint sets and a about 5 books of coins…
I don’t know what I have in my hands but from what I’ve been reading, proof sets shouldn’t have these types of issues? The ones that have are sometimes worth something? I do see doubling in some of these coins as well as what we all see is the major penny blemish.
So I guess I’m just wondering if anyone can guide me and let me know if it’s worth sending this coin to PCGS or any other grading company?
I’ve also got a bunch of other coins which look like error coins I’m just not sure because like I said I’m just learning about all this now as I’ve kinda fallen into a bunch of these bills and coins.
Thank you very much for everyone’s help.

Corrosion on the cent is not an error
Proof coins sometimes look doubled due to the mirrors. You would need much better pictures. But if you see doubling on multiple coins, that is what you're looking at.
Sorry, but no premium.
The cent appears to be corroded.
The doubling you see is likely to be mechanical doubling or just an artifact of the lighting.
Not worth it; the submission cost is more than the value of the coin.
The coins that "look like errors" are probably damaged. This confusion is common to new collectors. Genuine errors are rare, so one wouldn't just happen upon a bunch of them in the wild.
Howdy and welcome.
My suggestion is to learn about coins and how they are produced first before you attempt to dive into errors. As for the proof set in question, I see no errors on anything. However, the proof cent is definitely damaged by corrosion (or something similar) in its decades of storage.
Good luck!

many new collectors think they have errors that usually are just damage
