50c kennedy 12,69gr ???

What are silver logs.
Coins are struck not stamped.
I don't think any of us understand what you are trying to say.

There is nothing special about a coin that is within tolerance.

Doesn't matter if you can't find one that weighs more than 12.54 grams, the legal tolerage is +/- .259 grams. After over 100 year of practice trying to keep to the .09 tolerance it isn't surprising that they managed to keep the weights tighter than the legal tolerance.

No the tolerance were relaxed in the 40's when silver plummeted in price and it wasn't really needed to keep the tolerances that tight. If it was off a little more the cost didn't matter and it was easier to keep to the looser standard. I can't say for sure but it is also possible that around that time they finally stopped weighing every planchet.

 

it is exactly the opposite a lot of tolerance in 1964 when the price of silver was skyrocketing and led to the loss of the state given that the value of silver exceeded that of 50c facial

 

My English is not good and I often make mistakes with google translator, sorry.
... maybe you don't want to understand that the tolerance on pieces 50c of 1964 (900AR) is wrong reported by 0.259. The correct one must be 0.097. With blanks above 12.50 it was a loss of value for the state, which you may not understand.

 

Yes but the relaxed tolerance had been set much earlier when silver was low. In 64 rather than tightening the tolerances they just eliminated silver.

 

this is your consideration that I do not agree with and that is brought back by a printing error! ... raising the tolerances on 1964 is only on paper but in reality they were left at 0.097 because in practice today there are no coins with a tolerance of 0.259. You know of 50c1964 with a weight of 12.75 ???? if you find them you can post the photos here as I did. Thank you

 

the price of silver had already risen long before 1964 so that many 50c Franklins were merged. In these cases it would be madness to raise the tolerances on a coin with 900AR and at the mint they were not stupid. Subsequently in 1965 they went down to 400AR and raised the tolerances as coins with more than 600CU vary a lot in weight compared to 100CU, but also there was a mistake because it was still convenient to melt them. When a coin remains in the same chemical measurements but the weight is greater than 12.50gr it means that it contains over 900AR as heavier silver than copper and therefore these coins were of 925AR.

 

at the same size the diameter / thickness and the chemical composition change the weights for the 1964 coin (900AR was 12.50gr) for the 1965 (400AR was 11.50) the higher the copper level the less the coin weighs, on the contrary the higher the weight of silver the more it weighs the coin here you are explained that some 1964s weighing over 12.60gr contained 925AR. I hope I was clear

 

Have you done a specific gravity or XRF test to conclude your coin is Sterling silver? The mint never used anything other than 90% at the time. A heavy weight doesn't imply the alloy that was used. The difference in density between .925 and .900 is 0.36%. A coin that would weigh 12.5 g if 90% would weigh 12.55 g if Sterling. You could just as easily rationalize that there must have been a small percentage of gold in it to bring the weight up.

 

Okay, was not logged in so have to re-type this...Silver was $1.29 per ounce in 1964 (at least that is what google says). A 90% silver half dollar at 12.50 grams has 0.3617 oz of pure silver or 46.6593 cents of melt value. At 12.759 grams (upper tolerance limit) it has 0.3824 oz of silver or 49.3296 cents in melt value in 1964; both under face value of 50 cents. 2.6703 cents of difference.

Math...you can't argue with it.

 

The silver content of the planchet did not change, the dimensions of the planchet is what changed its weight. It was 90% silver content in 1964.

 

And no!!! All history books record multiple brokers that have collected and merged millions of 900AR coins in the years '64 / '72 including the 50c64 Kennedy. Do you think they were stupid? ... unfortunately, in those years, silver is also over $ 2 per ounce

 

There's a somewhat popular English saying: "Extraordinary claims require extraordinary evidence."

The claim that some 1964 half dollars were minted from .925 silver instead of standard coin silver is certainly "extraordinary". In fact, I'd say "ridiculous". It would take evidence to change my mind, and I suspect to change anyone else's mind here.

Having said that, I've posted before about coin weight tolerances, and my concerns about taking a commercial "Coin World Almanac" as the definitive word on official Mint tolerances. I'd rather see primary sources (legislation, internal Mint documents) verifying those tolerances. If, as you say, they've retracted that tolerance figure "on many sites", surely you can link to one or two of them?

 

Of course I showed an extraordinary 50c64 which weighs 12.69. Apparently no one else who owns 50c64 (ms65) can do it !!! Because all are below the 12.60 standard. Do not talk because you do not weigh your and post photos of pieces at 12.69 since you consider the tolerance "regular" ??? Show the opposite !!!

 

You show a coin that supports the tolerance claim cited previously and refutes your claim of tighter tolerances. And you provide no evidence of non-standard composition.

How could I satisfy you, short of weighing every 1964 Kennedy half in existence?

 

Doesnt matter what happened after 64 as silver content went down from 90 percent to 40 percent. When the price of silver went up people started hoarding the silver coins. What does that have to do with your original post? Your half dollar is worth its weight in silver. Nothing more.

 

Everyone talks but nobody can find 50c64 with a weight off tolerance of 0.097. Do you take pictures ??? Since it is a regular weight, even yours should weigh OW. I want to see how many you find !!!

 

We have been down the rabbit hole of primary sources on weight tolerances. They are not set by legislation but the Secretary of the Treasury. The weights and compositions are set by legislation and those are easily found. There are references to tolerances being set at the discretion of the Treasury Secretary, but actually finding any documents where they are laid out is the tough part.

 

Gianni you are making this a bigger deal that it is. I know you want it to be.

The only thing that will help bring better value is it's condition.

This is a common coin.
Nothing you have provided will make it worth anything more.
It may get a slight tone premium but it will be small.

 

The problem is that people keep talking but nobody can post 50c64 with a weight of 12.69. These are the facts.
