Mintmarks were punched by hand into coinage dies until the early 1990s. They can vary in style as well as in position.

Welcome to the NGC chat board. Sorry, but I don't think that this is an "S over D", a variety not known to exist on a 1978-S proof dime. It appears to be the normal blobby "S" mintmark that resulted from a worn mintmark punch, as is commonly seen on proof and other "S" mintmark coins of the mid to late 1970s. The deterioration of the punch led to the introduction of the thinner "type 2" "S" mintmark in 1979. If you still think that this is an overmintmark variety, please provide a better, less brightly lit image from your computer itself, not a screenshot. It is preferable to provide cropped images of each full side of the coin, as well as pertinent close-ups.

1925 Fort Vancouver commemorative half dollar, PCGS graded MS 64:

As there are no pre-1793 U.S. coins listed under VarietyPlus, this piece would not be attributable as a variety. Clash marks usually aren't classified as a mint error but are regarded as a "die state". This Fugio copper was also struck somewhat off-center, so it is possible that it could receive a "mint error" designation if that service were requested, but I wouldn't count on it. The main rationale for submitting this piece to a grading service would be to authenticate it and determine that it has not been altered. The clash marks are obvious, and shouldn't need to be stated on a grading service label.

Welcome to the NGC chat board. Please note that the Coin Marketplace forum is devoted to offers to sell or buy coins in accordance with the Guidelines posted at the top of the forum, not for questions about coins. Such topics are welcome on the "Newbie Coin Collecting Questions" forum or the "U.S., World and Ancient Coins" forum, where they should receive better attention. I have requested the Moderator to move this topic. It would also be helpful for you to post better-cropped photos of both sides of the coin. The missing details on this coin likely resulted from the reverse die from which it was struck being overpolished or filled with foreign matter. These sorts of anomalies can be interesting but usually don't make the coin worth much of a premium. I strongly recommend that you don't touch a coin that you want to preserve with your bare hands, except by its edge if you must. Presidential dollars, which are largely composed of copper, zinc and manganese, are particularly susceptible to discoloration and spotting from exposure to skin oils.

This 1942 Walking Liberty half dollar appears to be a proof, not a circulation strike. Based upon the photos, I would estimate the grade as PF 65-66.

True, but an 1882-CC could still be worth $150 or so.

1899 Liberty double eagle, now NGC graded AU 55:

Welcome to the NGC chat board. These Morgan dollars are all heavily and, I think, unattractively toned--we used to say "tarnished"--likely artificially. and perhaps to disguise an improper "cleaning". I can't evaluate them further without clear, cropped images of each side, at least similar to the larger photo of the obverse of the coin dated 1882. We can't even determine at which mints the coins were struck without seeing the reverses, which could make a significant difference in their values. The inadequacy of the images has nothing to do with this site, on which you will see many higher quality images.

1903-O Morgan dollar, PCGS graded MS 64:

The coins referred to in the link you provided were not intentionally sold or issued by the U.S. Mint, nor would they have come in packages like yours. You would not have been able to buy them like this. They were either errors struck on wrong planchets or were experimental strikes. They were either accidentally mixed with coins issued in bulk bags for circulation or, more likely, smuggled out of the Mint by unscrupulous employees for sale to coin dealers. Two mint employees went to prison for similar activities related to the State quarter obverse/Sacagawea dollar reverse "mules" that appeared at about the same time. What you bought as a child were undoubtedly normal State quarters that were "gold" plated by private parties after they left the mint. They were widely advertised to the public in mass circulation magazines such as TV Guide. I have seen many such offers. Undoubtedly, many thousands were sold. They have no value to serious coin collectors and have nominal value as novelties.

Yes, it is better to leave U.S. government issued sets like yours in their original packaging.

As usual, the author has provided a nice photo essay about a convention I'm not able to attend. The photos don't automatically appear on my computer screen. I had to click the first photo in each group to load them and advance through them one by one. I would like to note that the "beautiful duck" isn't a duck. It's a Canada goose.

There are genuine 1878 7tf Morgan dollars with the "Reverse of 1879" (scarcer than the "Reverse of 1878", but not rare), but this one is a fairly obvious (likely Chinese) counterfeit as indicated by, for example, the unusually narrow obverse rim, mushy details, odd color and lack of bagmarks. If you thought that the coin might have been genuine, you shouldn't have been holding it in your bare hand.

Welcome to the NGC chat board. I agree that this is likely a damage to the mint mark that occurred after the coin was struck, not an "error" or die variety. If the anomaly on the mint mark had been in the die, all coins struck from that die would show the same anomaly, and this should be a die variety listed on the vamworld.com site. The coin has many other nicks and abrasions from bag storage and circulation and appears to have been improperly "cleaned".

Multi-coin holders are "only available for select bulk submissions of certain coin types" upon confirmation with NGC Customer Service. See NGC Coin Holders | Holders for Coin Protection | NGC. The submission form allows the selection of "oversize", "thick", or "mega" holders but not "multi-coin" holders.

Welcome to the NGC chat board. The NGC Registry forum is for topics relating to the NGC certified coin registry. Questions like yours are best posted on the "Newbie Coin Collecting Questions" forum or the "U.S., World, and Ancient Coins" forum. (The Administrator will likely move it.) You should post clear photos of both sides of the coin that have been cropped to show as little as possible of the surface surrounding the coin. Your coin appears to be from Panama.

Mint errors (as opposed to die varieties) are classified by type of error, not by date or mint. They occur to individual coins as they are manufactured, so, each one is unique in its exact appearance, and the date and mint are generally irrelevant. Die varieties, including doubled dies, are due to specific characteristics of dies, which may produce hundreds of thousands of coins, each or at least most of which would show these characteristics, so they are listed by date and mint. If your coin's anomalous characteristics were created at the mint, it would be a mint error, not a die variety.

Welcome to the NGC chat board. What is your question? This forum is for topics pertaining to the NGC certified coin registry. If you have a question about this coin, you should post it in the "U.S., World, and Ancient Coins" forum or the "Newbie Coin Collecting Questions" forum, preferably with clear, cropped photos of the coin. If you are asking about placing this coin in a registry set, please note that ancient coins are not eligible for the competitive registry but may be placed in custom sets. See the following topic: https://boards.ngccoin.com/topic/432633-ngc-registry-where-do-i-add-my-ancient-coins/

Welcome to the NGC chat board. Many ordinary State quarters were plated or coated with a gold-colored substance by private companies outside the mint for sale as novelties. This appears to be one of them. Is there anything printed on the holder in which the seller appears to have placed the coin?

In my opinion, none of the coins or sets you have posted would be worth the cost of submission to a third-party grading service, including the ones that you purchased in NGC and PCGS holders. Dealers get bulk discounts for such modern pieces, they hope to make money on the few that receive "70" or very high grades for their issues (unlike the ones you bought), and they usually sell the others at cost or for a loss but still for more than the coins could have been purchased in their original sets or uncertified. These dealers also have the knowledge and experience to determine whether the coins they submit have a reasonable chance of achieving sufficiently high grades, which you don't. Unless an individual coin is worth at least several hundred dollars, it isn't financially worthwhile to send it to a grading service. You should enjoy your proof and uncirculated coin sets in their government holders, which adequately protect them and keep them in their historical context. You would have pay NGC a minimum of $19 per coin to have them grade and encapsulate these coins, plus at least $38 per order in processing and return shipping fees and your cost of shipping the coins to NGC. Your money would be better spent learning how to grade and otherwise evaluate coins yourself. (The purported error or variety coins you purchased in the cardboard holders may not actually be such, and the dealer may have been incorrect about them, in which case they might not be worth what you paid.) In your case, it is also important that you learn the English language well enough so that you may better understand books and websites in English. Some of the books and other resources you will need are described in the following forum topic:

1905 Liberty nickel, PCGS graded MS 64: Photos courtesy of Stacks Bowers Galleries.

Welcome to the NGC chat board. Your 1957-D cent resembles an in-collar multiple strike where the planchet (blank) rotated between strikes, but I strongly suspect that it was fabricated (faked) outside of the mint. The multiple images are too localized and only seem to appear on the obverse. See https://www.error-ref.com/?s=multiple+strikes for images and descriptions of genuine pieces. (A multiple strike is a mint error that occurs to a specific coin while being struck; a doubled die, which this definitely isn't, is a die variety caused by doubling in the die itself.) In addition to awaiting additional responses on this forum, you might want to post this coin on the CONECA forum at https://board.conecaonline.org/forum. You can also request an opinion from Jon Sullivan, a respected errors dealer, at https://sullivannumismatics.com/contact-us/.
