Yes off the top of my head I was thinking 1.9, so 2 missing clad layers have to be around 1.5 and super thin.
NO! Nice idea, but you made a few errors in your initial assumptions. Clad dimes are made from a 3 layer "sandwich". The outside layers are 75%Cu/25%Ni and the core is 100%Cu. You also need to use the specific gravity of pure copper and 75Cu/25Ni in your calculation. The good news is that they are also very close. Having said all that, you have an environmentally damaged coin. Nothing more
It comes down to moderation. How many times does a new poster have to post some damaged coin and INSIST they have some rare error while the rest of us shake our heads? The mods need to start deleting or closing these ridiculous threads.
All we can do as members is to give honest answers and not argue with new members that already know they are correct. It's impossible to make someone learn if they don't wish to.
There was a lengthy argument about doing EXACTLY this (and I wasn't even in it, imagine THAT!) and suffice it to say this suggestion ain't gonna happen. Site management has been down these roads before and they have things EXACTLY the way they want them right now. Else, they'd already be different.
If you are sure, it will only cost you about $50 with postage to find out. More money than the free advise you are getting here, but then it will be settled.
I understand the sentiment behind this kind of umm, err, advice, really I do. But what do we accomplish when we just punt and allow foolhardy things to happen. IN MY PERSONAL OPINION, we do the new collector a BETTER service, ultimately, by being stern and/or blunt to snarky. When I had my stroke in 2009, I nearly died. They asked my family about clergy to summon. Nobody told me rough truths until about Day 5. I ripped those doctors up one side and down the other. How dare they keep me in the dark! I told them, You give ME the straight unvarnished truth, or I'm transferring out of here TODAY!" The hospitalist was taken off my case immediately and an hour later I was looking at my own MRI images with a new attending neurologist. I. Can't. Stand. P*ssyfooting. I'm also no millennial, and I never watched Barney the Dinosaur or the Teletubbies, either.
I have told people ad nauseum about seeing zebras when they hear a stampede. There are some people that will listen to the advice. This OP was not one of those. And I would bet he would think NGC/PCGS had it wrong too.
LOL! Oh no! Here come the pics of slab errors. The part I love is these guys who can do XRF with visible light and just their eyeballs.
No it won't. They'll just come here and complain the TPG was wrong, or the TPG changed/damaged the coin they sent it. Sometimes you just have to let the threads go unanswered ... I have a couple heavy posters who post junk on my ignore.
lol (1) that marza beck video dude, and (2) coin addict Coin Life is a lot happier not seeing those posts.
