OP, for your un-plated cent, make sure you also click on the two links that say " Here " . http://www.error-ref.com/unplated-cents/
Seriously, Einstein? You honestly have the gall to, and think it wise to question the intelligence of others all while writing in a manner that would result in a failing mark even for the average second grader? Your coins, like your thought process and behavior, are garbage, and is as simple at that. Too bad you're unable to get your head out of your behind long enough to realize this. Asking yourself if you can read... great job, genius!
With hate? Go back and read everyone's responses. Not hateful at all, just giving her our opinion, which she did not want apparently, even though she asked for it. The only hateful responses were hers.
I really don't care . No one could post a link to error-ref, to show the OP on her un-plated cent . That's how you show people what's going on . And no one knew her quarter has glue on it . Remember shes a new bee . And for every action, there's a reaction .. That's why I said what I did and I don't care what anybody thinks either .. No skin of my nose .....
she wanted opinions, but did not want to be told them. how is that hate ? people will learn as they go. better to get opinions from people that have been collecting error coins for many many years. these collectors know what they are talking about. in a good way she might learn from this mistake and get a second opinion on her coins in the future. coin collecting is evolving and anyone can always learn more about coins from collectors that have more experience.
The venom is really starting to drip from this thread. But I do look forward to see what the NGC says about OP's coins.
You seem to be an expert yourself, waaaaaay above these dumb folk here who have spent 40 or 50 years studying millions of coins. So do what you decided to do before you ever came on this site, send them in. Your local dealer and the grading service can each make a few bucks off of you, you find out you have coins worth a total of 26 cents and everyone is happy! Coin # 1 is covered with glue. Coin #2 has had it's thin copper coating removed outside of the mint. Most likely with a weak acid. Could even have been soaked in Coca-Cola.
I get phone calls and emails with coins exactly like this every single day. I don't mean to 'pile on', but all of the other posts here are correct - both coins did not leave the Mint like that. It's a shame to see good money go down the drain, when submission fees/ins. postage, etc., would be better used to buy a book or two on errors or die varieties, or the Minting Process. No offense to the OP, but I absolutely assure you that neither coin will be certified as any type of error coin whatsoever. However, after doing this for 46 years as a full-time Mint Error dealer, I also acknowledge the folks like to believe what they have is valuable, and worth sending in. I try to tell them that just because you find a coin that looks 'different' doesn't automatically mean it's a mint error coin. Please report your results next month when you get the two coins back from NGC.
Now you're sounding like a pouty two-year old. Just because others took a different route, this in no way means they didn't know what we were looking at. You see, not everyone feels the need to try to show how much they supposedly know at every opportunity, even going so far as to make it up as they go along. There is no wrong or right approach, Rick, but what there isn't is a "new bee" involved in this thread. A "newbie", yes, but I'm doubting she's an insect even if she stings like one....
I find it interesting that you appear to an experienced collector based on your comments regarding submissions to TPGs, but you missed the obvious foreign substance on the quarter surface. The biggest giveaway are the circular features, which were caused by bubbles in the glue/residue. A simple acetone dip should tell you if it’s glue. Based on the detail on the coin, I can’t think of another part of the minting process that could result in that type of defect. A shattered die wouldn’t look like this, and the pressure from the strike would have “smoothed out” the high points from a defective planchet (they could still be visible, but not at the relief in your pic). From your pics of the 1990-D, it still looks like there is plating and the color may be due to environmental damage, but sometimes pics can be deceiving. The reverse shows a lot of copper color, but once again, not sure of the pics. The production process plates zinc planchets after they are punched from a strip. The planchets are then immersed in a plating solution, so I don’t see how it’s possible to have one side plated and the other side unplated (look at the link Rick posted). Another thing that immediately stood out is what appears to be long plating blisters under TRUST (and possibly behind Lincoln’s head). Did the dealer suggest doing a quick XRF scan? Many dealers, jewelers and bullion buyers have these units. A short test would easily show if the surface was copper or zinc. FWIW, I don’t think the plating was acid stripped (but am not positive and open to other interpretations) A knowledgeable numismatist should have suggested the acetone bath and XRF test before sending the coins to NGC. In my opinion, your dealer is not a numismatist, but simple coin sellers, and their lack of knowledge just cost you some money. As others have said, I think you should find another dealer who knows more about coins. Finally, I am basing my comments on your pics and not coins in hand. If these do come back as authentic mint errors, please share the results and feel free to shoot an “I told you so” my way.
I doubt that the OP will post anything now.. I tried nicely.. Fred tried nicely also. We gave our explanations but it is up to the new bee, umm I meant newbie now ✌ peace ✌
