69 kennedy half 90%??!!

If the total weight is supposed to be 11.5 grams, a 1/8 in hole simply is not enough surface area to consitute anything close to a half a gram. I mean, think about what you are suggesting. You are suggesting that a 1/8 inch hole makes up 1/23 of the total weight of the coin? Or, 22 more 1/8 inch holes and the coin would be gone?

I just do not think so.

Your coin is 40% silver. The breakdown of silver content is outer layer of 80% silver, 20% copper surrounding core of 79% copper, 21% silver. How accurate is the testing that can determine the 10% difference on the outer layer?

 

Oh my, how many times do we have to say that it's 40% silver. It's a damaged 69 Kennedy half that's worth it's metal content at this time since there's a huge hole in it.

 

I can spot 40% Kennedy halves by the edge any time.
The Red Book actually says bonded to an inner core of .209 silver.

 

I think your jeweler friend needs to educate himself on silver coins and silver clad coins from the mid to late 60s.

It's a 40% silver, .1479 ounces.

 

There are a lot of 40%ers that are visibly clad.

 

Quantitative reasoning: this is how it's done, folks.

 

@JeffB:

That looks like a sweet rim I'd like to have on my car!

 

Personally, I think the jeweler tested it for silver and then simply assumed it was 90% since most non-collectors are totally unaware that 40% Silver coins even exist. Where on the coin was this tested anyway? Aside from specific gravity, exactly how do you test for something being silver anyway?

 

As best I can tell, you put nitric acid on it, and watch what color it turns. I'm a little suspicious of this test, based on the chemistry I know that's behind it, but it seems to be the standard.

I've got a set of employee-reward rounds that I bought on eBay. They weigh 1 ozt (31.1-31.2 g) each, and they're slightly smaller in diameter but slightly thicker than an ASE. I dug into the edge on one of them, and it looked like it was uniform all the way down. I'm pretty sure they're .999, or sterling at worst, but I'm going to have to test them, and nitric acid isn't something you can just pick up at the drugstore any more. I've been thinking about making some from drain opener and fertilizer or saltpeter, but haven't worked up the nerve yet.

 

Post it on ebay explaining the the jeweler said it was 90% and let the market decide what it is worth! :devil: ointnlaugh:

 

Absolutely true..

 

I would just sell it to him as 90% and have him buy a bunch more from me and we can split the profits....

 

The chances of that being 90% silver is the closest number to zero. One way to be sure is to have a metallurgy test, but that might not be worth your time for it is only a 40%.

 

I'm surprised this thread made it to three pages, kind of.
Anyway, this is more of a lesson now. 40%ers have a few different looks, some edges look all white, some have a light/dark/light look, and BU ones have a white/red(brown)/white look.
Here's a few rolls of 40%ers. They're all 40%, but the pic wasn't taken to highlight those, so bear with me. I just cropped it.

You can see that many look clad, but of course, different than CuNi clad.

 

O MY GOD!!

your not going to believe this and if you dont i honestly couldnt care less!!
so with no coin shops any where close by i went to a pawn shop who has a small collection of coins in his shop and i have talked to him a few times about coins, he is way over priced, and is known in the town for giving you pennies for your stuff and selling it for way more than normal pawn shops would..

any way i took the coin to him he laughed at me..
ha, he took it to the back come back out and said,
"there is nothing special about this coin i promise you it is not 90% but there is a small double die error not worth much, but i will give you $100 for it right now." i said can you show me the error and he comes up with some crap about just dropping and breaking his loop.

I have tried to sell him errors before and he always says I do not want errors!
so i say ok thank you i will keep it. he says i would like to have it and keeps offering me money until he gets up to $450.
then gets extremely mad hands me my coin and tells me to leave.
when i ask why he wants it so bad he says, "this coin with the hole drilled in it looks just like the one my mom gave me when i was 15 she kept for the day i was born, and it just reminds me of that and i lost that coin she gave me and would give anything to have it back.

I THINK I HAVE SOME THING HERE!!!!!!!!!

 

It's a 40% half. I can't explain your weight anomaly (scale possibly not calibrated correctly?), but splurge on this little tool and I'm pretty sure you're going to find the definitive answer to any kind of question like this 99.99% of the time.

And turn to this page:





Not trying to be a douche, but it has greatly expanded my knowledge of US Coins. If I have a really tough question, I check the RB again. If I can't find an answer, I search the forums. If my search returns nothing, I post a thread. Just a friendly tip, cuz.

I got the hardback for $12 USD at a nearby flea market. I'm sure the local bookstore has it in stock as well. However, you can get one of those laser guns that test the metal's density (was showed on Hardcore Pawn, I guess it's a metallurgy testing device) but that would run you around 12-15k...not quite cost effective. IMHO I would try to sell it to your jeweler buddy for at least 10 bucks, just so he can take the same advice.

You're right, I don't really beleive it.

EDIT:

Detroit represent! That show's pretty fake though, from what I understand.

 

He offered you $450 for that thing and you kept it? I would have been sprinting out of the pawn shop with the first 100 bucks he offered thinking he's gonna call the cops because he just got bamboozled. If you aren't leveling the thread, then you should probably take that thing back to him and get your $450, if he still offers it to you. And BTW, pics, or it didn't happen (your sale receipt).

 

Absolutely my friend, but you learn quite a bit watching the boob tube these days.
