I don’t see how that would have an effect on the weight. The planchet would still weigh the same as it did before the coin was struck. Assuming an accurate scale, I see the three most likely reasons for the low weight as: underweight planchet, counterfeit, or some gold having been removed. If it is one of these, I hope it is the underweight planchet.

A half eagle minted between 1873 & 1929 has a tolerance of plus or minus .016, so acceptable weight would be 8.343 to 8.375, assuming an average weight of 8.359. Figures from the Coinworld Almanac. Your coin appears to be a good bit underweight.

He is asking for an evaluation. The coins are only worth face value, which is one cent US (1/100 dollar) each.

Welcome to the forum. It is a shame to have to inform a new member that their very first post is of a coin that isn't what they thought it was, and even more of a shame to have to tell them that they have been ripped off, but that is the case here, I'm afraid. Your coin is not a mint error. As others have said, it was fabricated after it left the mint.

Welcome to the forum. If your question is about the unusual color of your nickel, it is most likely caused by environmental damage or damage from extreme heat.

Did I really call the Lincoln memorial Monticello? I must be slipping. Thanks for the correction.

Welcome to the forum. If by “skinned” you mean the missing metal on the right front of Monticello, that is the result of zinc rot. Your coin has a zinc core that is plated with (mostly) copper. When the plating gets a nick or scratch, the zinc inside is exposed to the air, and starts to corrode. That often causes more of the plating to flake off, exposing even more of the core, and perpetuating the process. This is very common on damaged cents minted after the composition was changed in 1982.

What was the hammer price?

I have to admit, statements like this cause some concern. You may be an experienced numismatist, but I assume you are relatively new to the coin world. If I may be so bold as to make a suggestion, why not post a picture, obverse and reverse, of one of your coins? That way members can look at it and try to determine if it actually is an error. The reason I say this is that if you're looking at coin pictures online, chances are they may not be pictures of genuine errors, depending on who posted the picture. There is probably as much or more false information on the internet as there is true, especially when it comes to error coins. Edited to add. The picture of the capped die cent wasn't showing up when I posted the above reply. That definitely is a genuine error. My apologies to the OP. Still, you might want to post a picture of yours, just to be sure.

You can continue to play devil's advocate or "defender of the downtrodden" all you like, but, rest assured, the majority of the members of this forum strongly disapprove of this guy's tactics, especially since he's been repeatedly called out, and continues to do it. It isn't "harmless conduct." It's the forum equivalent of spam phone calls and junk mail, and we don't like it.

For the sake of accuracy: only certain types of double strikes are considered planchet errors. These would include, for example, a cent restruck by nickel dies, or a foreign coin restruck by US coin dies. Many of these, probably the majority, are created intentionally. Most other forms of double strikes or multiple strikes are considered to be striking errors.

I' m sorry, but that is damage on the rim, not an error. And, the raised parts look like clear glue from your pictures. Try a soak in acetone and see if they come off.

This forum is not your personal venue for hawking your coins. The marketplace forum is the place to sell coins. Please stop spamming this forum. And, while I have your attention, intruding on other posters threads, trying to sell them coins for which they are not looking, is in poor taste.

Or, you could try to learn from the experience and see where your grading skills need improving.
