Whenever I find a doubled die which does not match the references I use, I go ahead and check the adjacent years if it’s the reverse die to see if it was reused. I check the listings on pcgs, ngc, variety vista, and wexlers. does anyone know of a more complete database? ANACS pop report lists many but I can’t find photos of them. I don’t understand why the CONECA database isn’t accessible either.

Hoghead, thank you for putting slabs on scales and reporting numbers, very helpful. I cracked my coin out and it does not weigh enough to be a 90% silver planchet. yes, the part about pattern/prototype/trial was smartasserry aka trolling here are photos of the doubled die if it interests you https://imgur.com/a/6spDSFR

Imagine being so arrogant you think you know the metallurgic composition of every coin in someone else’s collection, and also calling that someone else delusional. but I think you actually might be right, it’s not a wrong planchet, that implies an error, given the reverse die is a ‘64 it seems to me it’s a prototype or pattern or trial piece (whats the difference, anyway?). I’m not jumping to conclusions or offering this for sale yet though, just asking what the tolerance of a slabs weight is and noting the two slabs weigh .83g different! Why does this upset you so much? all I asked was what your recently graded halves weigh in their slabs. If you have some lying around and a scale just help a fellow collector out with useful data. obviously wrong planchets are super rare errors else they wouldn’t be so valuable if you believe they are so rare it’s pointless to look for them well then there is zero chance you fill find one. You can’t possibly know what I do and don’t have. THAT is insane JPM, if you weighed each set and there was a 1g difference between the two in their holders then yes, crack them out!

Wow such hostility when asking such a simple question. Coin grade doesn’t add much value I’ll probably just crack it out so I can really verify it with the specific gravity test you all insist is the standard. interesting though how it’s a DDR (which is why I submitted it) but after getting it back and being confused/disappointed by the lack of attribution, further inspection revealed the reverse is not the 1965 SMS FS-801 but rather the 1964 business strike DDR FS-801. I don’t think this is coincidental. 0.83g is the difference between the two. I’m sure the graders noticed. Why it wasn’t attributed is a different matter entirely. Get it? Different matter… I’ll show myself out. so from my searching I don’t see any known examples of a 90% silver ‘65 half. The quarters go for up to $20k right? What do you think a half would go for?

The most recent slab design - does it have a tight tolerance on weight? Would it be appropriate to weigh two slabbed coins and conclude one is on a wrong planchet if the difference matches the difference in planchet weight? If anyone has a few recently slabbed halves and could weigh them and report back it would be much appreciated. Thanks.

I finally got my hands on a scale I trust and did an SG test and it turns out the coin is not silver. Deleted the WTS post. It was never my intention to scam or deceive, hence the discussion on testing methods and what would constitute proof. I really don't understand the hostility. There is a lot of conflicting information. For example, in the Cherry pickers guide the author states NOT to look at the edge of the coin to differentiate Cu-Ni clad coins from 40% Ag. I suppose its possible the coin is plated, but I don't understand how only the obverse/reverse would be plated and not the edge. I suppose its also possible that since the coin was dipped in E-z-est and many silver coins had been previously dipped that caused the change in color when exposed to sulfur, but I don't think such a small amount of silver could make the coin shine like it does or pass the tissue test.

Please, do link me to a procedure for performing a specific gravity test to three sig figs, and stop slandering me with accusations of fraud when I came here to discuss the possible ways of testing. As I said in the WTS thread, I'm fine with mods deleting it. I'm fine with restricting or monitoring my DMs. I'm not interested in selling it until it can be proven one way or the other.

I'm not a scam artist, I've tried to have a useful discussion about what tests I can do to determine its metal content. I've proposed using ultraviolet light reflectance, exposure to sulfur, ping test, tissue test, etc. All y'all have told me is to do SG and/or get it graded. Y'all insisted I do a SG test, which I did, which also confirms it is silver. I understand it is strange the edge is red. I am not claiming to understand how this coin came into existence. If I could delete this thread and take down the WTS ad until I figure this out, I would. If mods want to delete the threads go right ahead, I do not care. If you want to leave it up, I also don't care. Has anyone ever had the experience of being approached at a gas station or electronics store parking lot by someone wanting to sell an iphone, speakers, laptop etc, usually at well below market price? The low price is a red flag for a scam, which is why I raised it. I do not understand why no one will answer the basic question of "what test would prove it to you" or otherwise engage in the discussion of at home testing methods. I didn't come up with the tissue test by the way, I saw this post and thought it was valuable knowledge y'all would appreciate, given that it can be used through plastic for example when the coin is in a binder, holder, album etc and you can't see the rim. https://www.cointalk.com/threads/silver-tissue-test.245035/

The specific gravity test in fact confirmed it was silver. Not with a great degree of confidence. Did you even read my post? The tissue test confirms it is silver. The sulfur exposure test confirms it is silver. I have plenty of examples of 60s and 70s Kennedy halves but none which are half red on one side of the rim and silver on the other side. Very curious. I didn't say I don't trust dealers or coin grading companies, I'm simply asking the hypothetical (out of curiosity), if they didn't exist and you wanted to purchase such a coin from someone on a forum such as this (where you might not trust the seller) what tests would convince you it was real and how would the person need to present that test (live stream of said tests being performed?) to convince you. Very strange how many experts here refuse to answer that simple question. "it doesn't look like anything to me" you all keep saying

So what do you think it is then? Have you ever seen a coin with a rim like this where one side is mostly red and the other mostly silver? If its plated, how do I tell? I'm willing to take down the sale ad until it gets figured out but my questions about exactly what tests to perform to prove its silver and genuine have largely gone unanswered. I did a specific gravity test using both a plastic set of tweezers and then a bent paperclip to lower the coin into distilled water but the reading on the scale fluctuates so much I don't find that test conclusive. A CuNi clad coin is 8.92g/cm3 and an Au clad is 9.53g/cm3 and I'm measuring 9.6+/- .4 g/cm3, which also supports my belief the coin is silver and not just plated.

You omitted the picture of the rim which shows only half is red. Quite the oddity. So that y'all don't think I am a scammer trying to bait someone into purchasing the coin hoping to quickly flip it, I've decided to raise the price to what I believe is fair market value, non negotiable. $13,700.

I would just like to add, if I was a scammer, why on earth would I have mentioned the XRF test? I could have just as easily told a story about going to a jewelry store and having it tested and being told it was silver. I mention that because I am an honest person, unlike the people who have wasted considerable time and effort attempting to deceive me. I wanted those people to know they had failed, and that they are pathetic for making such attempts. I want all of you to know that there are people in this world so petulant and pathetic they will corrupt anything and everything they can to punish those who challenge their cult and its dear leader. Do not let them tell you up is down, black is white, or any other obvious lie unchallenged.

I will report CG tests when I am able to obtain an accurate enough scale for that measurement to be of value, but even then unless I live stream a video of said test (live stream because a pre-recorded video might be edited) you will probably still insist I am lying. Below is the message I sent to forum moderators when I reported your post. GOOD DAY SIR.

in performing a scientific test we have what are called "controls". The idea is you do the test not only on the items of interest, but also on others to verify the test works as expected. I placed dozens of coins in the container, some of which were silver junk, some of which were clad junk, and some of which I suspected were silver because they passed other tests like the ping and tissue test. I divided the controls into two sub groups, one group was dipped in e-z-est, rinsed with high pressure water, then distilled water. This ensured there were no other contaminants that could have caused a change in color. The '71 here was also dipped and rinsed for the same reason. The coins I knew were silver behaved like the coin discussed here - yellow toning developed on the part of the coin protruding from the 2x2. The coins I knew were copper nickel clad did not develop any toning in the exposed area. The test revealed this coin is silver, conclusively. If you insist I am lying or the test performed is not conclusive, please answer the question "what would it take to convince you?" Everyone commenting in this thread insisting the coin is not silver and refusing to answer that question is clearly acting in bad faith.
