Strike doubling (or triple like your example) can be very interesting and dramatic.

A moment of weakness.

Without more information it is rather difficult to give you any information, not sure why you are afraid to share the coin type and date here, it is unlikely that providing that info would cause a rush to buy it before you can. However, in the absence of such info and using the limited info available (PF70) I will assume that you are looking at a very recent modern coin, and with the price I am guessing one of the recently released Morgan/Peace dollars. The best source for coins like this is to check on ebay for the coins that actually have sold in the past. Again not the listing price but the sold for price is what you want to look for.

Yes the thread ats is about Mr. Lange here at NGC, I think the member ats that mentioned his passing was a misunderstanding and more as a question. Best wishes to Mr. Lange and his family as he battles with cancer, I have never had the pleasure of meeting him in person but have always thought of him as a true gentleman, and amazing numismatist. I was hesitant to post this here but as it has now come up, this is from an email on the ANA advisory board that was posted ats: "My communication ability is limited by illness for now, My breast cancer has progressed to where it's affecting my brain. I'm unlikely to respond to most message, so please let my friends know that I'm otherwise viable and will be around for awhile. Share with anyone outside the company for now." Dave, David W. Lange

Congrats on your new additions!!

His own tests have already proven this coin is not what he claims, just a scammer or troll.

I bid $1, you pay the shipping. Let me know how you want the funds.

Looks like a good match to me, assuming that it is authentic.

100% strike/mechanical doubling, not a DDO.

It has been cleaned, looks like it was dug out of the ground and whomever did find it cleaned it to remove the dirt and (most of the) crud.

Both of the situations in your op are the result of improper storage. first off the 70's coins the halo can come from the coins having been stored in a coin album or folder and the album has produced the haze on the coin. I have seen on a few occasions where the use of restoration; by someone very skilled in restoration techniques; the haze removed and the coins returned to almost pristine condition. But usually that haze has eaten into the proof surface and an attempt to remove it leaves the surface of the coin damaged. The corrosion spot is the result of some contaminate that got on the coin and corroded the surface. this cannot be fixed in any way and the coin is ruined and the numismatic value is gone to most collectors. I cannot say what contaminate got on the coin, maybe someone sneezed on it, or coughed on it, contaminates can come from many sources; and it could have happened at the mint or after it was removed from the mint packaging. The 1984 proof looks to have been stored in a damp or excessively humid place, excellent photos but I cannot say for sure if the zinc core has been exposed and begun the process of zinc rot or if that is just some active verdigris. Either way I would not want to store any of these coins with any coins that you want to stay in nice condition. All three are sutible for placing into an album or folder, but none have any collector value

Impossible to say anything meaningful about the coin's surfaces from the photos, the coin does look to have nice details but it also looks "off", but that may just be the photos. To be clear I see no evidence of the big overdate for this date, I am posting a close up of the date for the important 16/16 overdate. I think that if you had the "big one" it would be obvious in your photo, and it is not, at least not to me.

Well as with all things toned it all depends on if the tarnish is pretty or not.

Welcome to the forum, I'm sorry but your obv photo become too grainy and pixilated when I try and enlarge the photo. You absolutely do not have a DDO-001, it could be that you have DDO-002, however, you would need a good close up of the date to see that as DDO-002 is very minor. From what I can see in your op obv photo it looks like a normal coin.

As you found there is some science that shows wood can out gas and have some effect on coins. How much effect is dependent on many factors, the type of wood, the environmental conditions like humidity, heat, and others. Desiccant is a must for every collector, but that only helps control the humidity in your storage area. I like the protection that the IS products offer, and I have for decades stored my copper coins in IS products. I use the IS albums and the double protection boxes for my copper slabbed coins. However, while I like, and use them, IS products are quite expensive so; there are several factors to consider when looking at storage options. If you live in a dry area of the country and plan to sell the collection within a short timeframe, then you really don't have anything to worry about either way. But if you live in a part of the country that is humid for the better part of the year, or if you prefer a more humid home and run a humidifier, then how you store coins can be important, again especially for very reactive metals like copper. The type of coins is also a big factor, gold is relatively inert and is not as difficult to store, silver also not as problematic for the most part. So the best advice I can give is look at the whole picture, environment, length of time you plan to own, and then decide if the IS products are a good fit for your short and long term goals for your coin collection. And I should have said so earlier, congrats on reaching your goal. It is an awesome feeling for collectors when they set out on a numismatic quest and achieve that end goal.

Well, first I would not keep them in those boxes, wood can out gas and cause some problems with coins especially copper. As to what to do with them that would depend, I have some sets too but stopped collecting them due to the storage space considerations. If I could get back most of the money I had spent on acquiring the sets I would sell them, but that is just me and I'm not suggesting that you should do so.

Welcome to the forum, my advice is to contact NGC's customer service and discuss the issue with them. Really your only recourse is to send it back to NCG so that it can be reevaluated for the correct mint. Mistakes happen and NGC may be willing to fix the mistake (assuming that they agree) at no cost, but that is a matter to be discussed with customer service. A few months back I had a US coin that was labeled incorrectly, these human errors we call a mechanical error; NGC paid for the shipping both ways and fixed the issue at no cost to me. My situation was slightly different as it was easy to see the label error as the label was for a completely different type of coin and graded as VF64 . I'm not saying that your issue will be fixed for free but I have found NGC very willing to work with collectors to fix problems.

Sorry to say that you have an expensive paperweight, knowledge is important when spending hard earned money.

This is incorrect, however what you could lose by having the coin reholdered is value. Depending on how old the holder is you could lose resale value by placing the coin into a new holder. Astute collectors know that coins in older holders are likely stable and any doctoring that might have been done would/will have already shown itself. But a coin in a new holder may have been freshly doctored and could turn in the future. Many people wrongly think that the only reason collectors seek out old holders is for the upgrade potential, but that is only one of many reasons that old holders are valued by collectors. So if the holder has value you will not only incur the costs (and risks) of multiple shipping and the fees at each service, but the possibility of less demand and value when you decide to sell the coin at some time. Having said that, if you decide that you must send your coin in to be reholdered by NGC you can then resubmit to CAC with a copy of your reholder paperwork to NGC showing the original cert number, CAC will charge a $3 fee to reapply the sticker assuming the grade stays the same.

If you ae talking about the individual obv and rev for each coin in your set no there is no specific background that needs to be used. Most use cropped photos on a white background, you can see an example by clicking on one of the sets in my sig line, or if available the slab photos that NGC takes. If you want you can add a background to the large area at the very top of the set, not everyone does so but you can.

A youtube video between John Feigenbaum and JA about this new service and it answers a few of the questions that I had. Video

So sorry to hear this news, hoping and praying for Sam and your whole family.

As I suspected the recent rumors that CAC would start its own grading service are now confirmed. Here is a link to a CoinWorld article outlining the new service, not a ton of details but this should get interesting. Coinworld

Congrats on those two new additions to your set!!
