The seller is either dumb enough or dishonest enough to call it a Bugs Bunny when it is manifestly not. Therefore, he's dumb or dishonest enough to pretend it's FBL. And of course he imagines it's uncirculated. Why doesn't he also advertise it as a cure for cancer and scabies? This seller belongs on one's personal blacklist (everyone needs one of those).

That one looks pretty natural.
In general, the helpful thing is to know how coins get cleaned. There are two methods: chemical and abrasive. Chemical means may affect only surface crudulation, or they may be caustic enough to attack the metal. Abrasive methods are typically either lateral (side to side) or circular (as with a Dremel tool). Often people combine the two, rarely with good results.
So with chemical, you are looking for unnatural color and/or residue. Especially if they don't like the result, cleaners will sometimes not bother removing all of the residue. With abrasives, you're looking for tiny scratches. A microscope is very helpful when assessing what has been done to a coin. The typical numismidiot--by this I mean someone who just decided to "get into coins," and thinks "if its shinny yo no1 will no if its unsurkalated so imma brasso it real good"--has zero idea the resources we have to detect and assess cleaning. We get them here every day.
For natural looks, a proof looks mirror-finished (and sometimes they are impaired). Its color may have darkened, but you're looking at the surface. Old copper tends to turn brown, usually a very appealing chocolate or caramel color. New copper is bright and, well, coppery--your penny is a good example. Silver can tend to darken over time; when new, in coins, it often has a sort of faint buttery color, but it can tarnish to charcoal flat black and still be uncirculated, as circulation status doesn't mean level of shininess.
A cleaned copper coin will usually have an unnatural coppery color, more pink than red-orange. Look for a coin with wear to the high points but too brightly colored. A cleaned silver coin will come out blast white, an unnatural color for a circulated silver coin. In the end, to get good at it, get a microscope and start examining coins. Even buy some that a dealer has marked down as "cleaned" so you can see what the symptoms are. Time invested here will pay off in better buying later.

It's not that it's impossible. It's that it is so vanishingly unlikely we may safely assume it's not an error, in much the same way as it is vanishingly unlikely that a single lottery ticket will win millions.

Or none at all. Then get all mad because one of us told them how ridiculous it was to try and assess a coin without seeing it. Stick around here long enough, you will see some of the least intellectually capable people you could possibly imagine. They could all ask the same questions as you have, get a plethora of tips and guidance from people who know their photography (unlike me), and we'd do our best for them. They don't. You'll see fifty-line paragraphs, accusations of racism when we have no idea what color they are, and open trolling.

The marketing opportunity is teed up for Zitsy, a site specializing in depictions of dermatological issues.

I assume the mole on his nose is part of the design.

That might be the very worst fake 1804 $1 I have ever seen.

I can see why you might assume that, but in fact we routinely talk about PCGS, ANACS, and the various JGS (Joe's Grading Service--my term for the various less credible outfits) in this space. NGC has never seemed to mind, much to their credit, even when someone blisters them. Very few of the posters here work for NGC; most of us are just collectors, some who do a little business as well.

So can arriving without a sense of entitlement. Good luck.

The rim is not melted. It's smashed. This looks like a parking lot coin, in that it got stepped on or run over while laying around a parking lot. Especially the weight of shoes and tires running over it, pressing it into the small rocks in the blacktop and scraping it, does stuff like this to a coin. I do not believe it was deliberate abuse, just happened. Probably no one who contributed to this mess was aware they were doing it.
As for unfriendliness, I'm not sure what you're seeing that would warrant that claim. You had your first reply within minutes, albeit not a very illuminating one, and no one has spoken abusively to you. You asked a question and have received polite answers. If that's unfriendliness, then I'm not sure what can be done.

Echoing what Bob said, if you are cleaning your coins, you are devaluing and damaging them. If you want to do your friend's son a real service, give him some uncleaned ones and inculcate in him why he should never clean them, why "shiny" does not mean "excellent," and that a natural look is always preferred. There are exceptions, but the short version is they are unlikely to include any coins you might have or are likely to acquire.
If you want to teach him even better, find an obviously worn coin that some [term for person of minimal discernment] has cleaned abrasively, and show him the zillions of little scratches under magnification. Just in case he's thinking "yeah, but they can't tell, so why shouldn't I?" Oh, yes, we can. That would really help him think in ways that would lead to an excellent collection.

It isn't.

Because what is shown in the photos (we didn't get full images of both sides, so we have very limited information, and can't examine even the rest of the reverse) is characteristic of mechanical doubling, and inconsistent with true doubled dies.

The problems are fundamental and insurmountable: keyboard inconveniently small, screen inconveniently small. On top of that, you can't just hang it off your shirt and go on speaker. It's wear a headset or hold the SOB up with your hand. I have one (I was third to last), mainly because flips were so expensive and a very stupid handyman managed to drop my last flip into a pan of water. However, I do not fundamentally like the modern phone. There is so much to hate about it (I refuse to use the s-word because that just feeds into the marketing gimmick; it's no smarter than any other damn piece of electronic equipment).
So what drove me to buy one? One, I wanted the ability to block unwanted calls. (NOT "spam" calls. Spam is undesired mass email. People have forgotten that.) Two, there are now and then times when it's handy to be able to look something up while out and about, or sitting at the TV. Three, it enables me to set up video recording on short notice, such as if stopped by the police. Four, as dinky and inconvenient as it is, when stuck somewhere waiting for this or that (doctor's appointment, car repair, take-out order), it does offer games and newsreading that, pathetic as they are on this tiny little thing, beat all hell out of 2019 copies of People or Motor Trend for short-term entertainment.
So I have it. But I hate it. I hate even worse that mine constantly finds little ways to try and shove Google down my throat. I now see how the data hydra has survived the desktop PC era: between getting you to use logins and passwords on a laptop and for the same things on your phone (Gmail, Faceplant, etc.), once the camel's nose is under the tent, there's nothing to prevent a complete dossier. Evidently most people don't care about that. I do. And while I can't stop it, I can refuse to just bend over for it. I can refuse to make it easier for them. So the rule on my phone is simple: Nothing Requiring Login. No bank, no email, no brokerage, no nothing, don't care, don't want, won't do, forget it.

I was never sure how many the pinball/video game company supplied when servicing the machines, but the ritual was pretty straightforward. If the machine chowed your quarter, you went to the counter and told Shirley or Zillah, and they gave you a red one, so it must have been plenty. In adulthood I came to realize that it was to avoid throwing off the accounting; by segregating the red quarters from the haul, they could pretty much be sure their income figures were correct while enabling the store owner to make people happy without having to keep a tally of freebies handed out.

If the quarter is red as in fingernail polish, it was probably a vending machine/video game/pinball replacement coin. In those days, vending machine suppliers and operators gave nail-polished quarters to the people operating the establishment so that when the machine ate a quarter, they could supply a replacement. They still turn up in change, though I assume that their use declined as most such games ended up in arcades where tokens came into use instead.
Be prepared for most of the "errors" to turn out to be post-mint damage. At the top of this forum are some guidelines I penned to help people post their coins correctly. Feel free to review them before posting--it will save you a lot of trouble and help us to help you.

If it happened, you'd do so just so that you could take a finger-smooching selfie. But I'd make it optional.

Your second-guess was right on. This looks to me like mechanical doubling, based on the shelfy nature of the second (lower profile) date image.

Bob's right. Here's the key hurdle for you to get over: the idea that coins need to be shiny in order to be nice. Coin collectors do not think that way. There are un-shiny coins that are Mint State, in that they have never circulated. Coin collectors prize the coin looking the way it should for its level of wear/handling/age. A penny would normally acquire a dark color in certain climates, for example, but also through contact with hands and pants pockets. In fact, a penny that has been cleaned to make it shiny will stand out to any seasoned collector as "badly cleaned," and if that collector is anything like me, s/he will say: "Was probably a nice piece until some yahoo got hold of it." Is a natural piece of red copper a thing of beauty? Surely. But the key word is 'natural,' and we know what it looks like.
Green stuff is probably either PVC slime or copper tarnish. We'd probably reserve "patina" for the overall rich chocolate brown hue that an older copper coin is likely to have. If the coins were stored in old tubes for a long time, the tubes probably deteriorated and coated the pennies with disgusting green slime, like Ghostbusters coins or something. Acetone will indeed take that off--I've done it. Otherwise it's probably verdigris, a sort of turquoise tarnish. In that case, there are two choices. If the coin is hugely valuable, you could have NGC take a crack at removing a tarnish that will grow worse over time (that's why they call it 'conservation'). If it were an S-VDB, for example, that's what I'd do. If it's worth very little even in untarnished condition, might as well try olive oil on it since there's no value to lose.
