Nominal weight for a clad quarter is 5.67g with a tolerance of +/- .227g. (5.897g - 5.443g). For the amount of wear and tear that the coin has seen, it wouldn't surprise me if it was under tolerance slightly due to metal loss. Get a new scale, one that reads to at least two decimal places.

Possible lamination error. Seems ok.

Interesting, I had not heard of this before. The only question I have is how much zinc needs to be present in the plating for it to be considered an error? If only based on color then your opening a can of worms. I would also assume that this is fairly common. EDIT TO ADD: It wouldn't surprise me if TPG's won't authenticate this type of error anymore.

A "retained" strike through, or whatever adjective you want to use, has been around for a long time. It's just that most are not significant enough for anyone to care about them. The OP's cent is not a doubled die and I see no evidence of a strike through on either the cent or ASE. I hadn't realized, or forgot, that the font was changed on the T-2 ASE's. Hideous.

I have never requested NCS conservation but when NGC recommends it I've always approved it and have never been disappointed. Acetone won't remove all surface contaminants, I soak most of my coins in acetone for 24hrs or so and they come out looking better but not like after NCS conservation. Maybe if I placed the container on an agitator/orbital shaker or had a fountain the acetone soak would net better results, something I'll be trying at a later date. I also, mainly, collect modern World coins which often don't have all of the pitfalls of U.S. coins like old cleanings, AT, and the like. To the OP's question, no, there is no way to tell if a coin has gone through NCS.

Always nice to find some silver.

Welcome to the Forum. You have a mutilated cent, not an error, return the coin and get your money back if possible.

Link to the auction listing please.

Sounded like they got themselves some gold, 250MM or so, and are backing the notes and coins with it. So it is not a fiat currency.? 250MM is not much, these notes and coins could be hard to come by if they are capping the release of all notes and coins to that number.

It's back up for auction, at Sedwick's this time. Let's see how she does on the second go around with a change of venue. https://auction.sedwickcoins.com/item.aspx?i=52420824 Opening bid 7k, estimate 10-20k.

I see that NGC corrected the points for the bond coin. Worse case you could have jumped on the ZiG coins when they come out, might not be to long of a wait since they have put the ZiG banknotes into circulation now or at least plan too on April 30th.

The Saskatoon Coin Club is one of my favorite websites. Nice find.

I'd consider the source. A newb getting burned and knowledgeable "dealer" or collector not, well, I would expect that 100% of the time. I do think that dealers or well known individuals do have an advantage in getting things authenticated through TPGs that would be returned as normal to regular submitter.

I'd try to find one in the OGP but if you could pick up a PF 69 for a lower cost I'd maybe consider that. Looks like you can buy a PF69 on ebay and the OGP for less than the original selling price from the U.S. Mint. What!?

The coin Jason posted is Pridmore 290, below are two, supposed, authenticated examples of Pr 291. They are a much closer match to the OP's coin, that's not to say that the OP's coin is authentic, or any of the other coins posted for that matter. Letters and numbers on the coin below look spindly compared to the PCGS coin with stems missing from the wreath, could be due to polishing but the upper loop of the "6" seems to be missing similar to the OP's coin. The coin below was pulled from an auction in 2023. Why? This coin exhibits full, or nearly so, details as opposed to the other two. Auction description: "KM-Pn35; Prid-291. A laudable and interesting Proof Hong Kong emission, Pridmore relays that this example is a Mule Pattern Cent, with the reverse of Prid-261 being paired with the obverse of Prid-288. The overall appeal of the example is only increased by the proof nature of the strike, with fully formed and crisp details and rims, with a fair amount of mint red being retained. Light tone even adds a touch of character, making this Pattern one that is certain to capture many excited bids." Which if any are authentic? I'm not familiar with these at all but only one of the three is of the quality I would expect for a pattern of this type.

3,600 points! Guess I was wrong about Xanno not being a threat. Seems like an obvious mistake which I'm sure will be corrected very soon.

How many ways can a coin be damaged? The world may never know....

Yes, it is a one year type and they made a boat load of them.

It's from 1989 I believe. All 50 yen coins from this date had the Kanji symbol for "first" in place of a western numeral for the regnal year, 1989 being the first year of Akihito's reign as emperor of Japan after Hirohito's death in January of that year.

Looks like two drill marks to me, one on each side. You can see where the drill bit or tool walked on the obv and both sides have what appears to be metal displacement. The alignment, meh, who knows. Damage is damage, doesn't really matter how or why.

CAC is still beaning coins.

Looks like a drill mark. PMD.

I assume that by "U.S. dollars" it is meant any U.S. gold coin, presumably double eagles. It would be interesting to know what U.S. gold was exchanged, type and date, but it's highly unlikely such information was recorded.

I thought this was an interesting little article. I had never really thought about how monies were exchanged between a visiting fleet or army and governments. I wonder how much gold was carried onboard and how much was deposited on a stop like this? You should be able to zoom in on the pic and read the article.
