@Zurie this was first posted on Facebook years ago. All the data come from the Mint report of each year. Was collected and assembly. Each year from the begin of the Mint must have the Congress permission to strike coins and they present the coins and the specs. Oh also the medals need the Congress approved for design , weight, diameter and the historical point. do you want me to post here all the mint reports from the begin?

PCGS, NGC, Coin World, the Red Book, Numista, and numerous online sources all state that the weight of a pre-1965 Roosevelt dime is 2.50 grams. The Coinage Act of 1873 mandated that dimes weigh 2.50 grams, and this did not change until the Coinage Act of 1965. I don't think there is any controversy here. The only source that says the weight is 2.527 grams is that old Facebook post, which I suspect was an error. |

Silviosi if you can find the one regarding the jefferson dime when possible that is the main one questioned. It is more accurate '2.527' vs 2.5 so its worth checking or point to the reports where others can look. Zurie, the official document from the mint/treasury this one comes from is only listed in grains not grams,shows 38.58 grains which I just converted to 2.499942g (2.5g rounded up) and a minimum of 37.08 grains = 2.402744g. It is just curious that there is a clearly well put together different document that mentions 2.527 vs a 2.5/2.50/2.500 so we will see if possible where that came from at some point.

Ok I will push up this from report. Not this night but I hope tomorrow I will be less busy. I think that peoples do don understand how complicated are those reports.
An example: On sites are push the numbers of the coins strike as a number of the coins, but never calculate how many was in the reserve, or retired from circulation or melted.
DATA I will do 'it. I have to look in 400 pages of report. I will pull out also the 1951 in question.

Zurie, the official document from the mint/treasury this one comes from is only listed in grains not grams,shows 38.58 grains @datadragon, I had some time to look into this some more. Here's an excerpt from a book published by the Bureau of the Mint in 1908. It notes that silver coin weights are based on metric weights by law, but since they wanted to use troy weights, they converted everything to troy ounces and grains. So 2.50 grams for the dime became 38.58 grains, which was the standard weight until clad coinage in 1965. That's why all reputable sources state that the weight of a silver dime is 2.50 grams. Regarding that erroneous Facebook post, it correctly notes that the weight of Franklin and silver Kennedy half dollars is 12.50 grams. Since silver coinage weight is proportional to value, the weight of silver dimes should be 1/5 of that, or 2.5 grams (not 2.527 as stated in the chart). There are some other errors in that chart; for example, the weight of a Barber quarter is 6.25 grams, not 6.221 g. I also included the section on the legal Weight Tolerances for the various coins, showing that the tolerance for dimes was 1.5 grains (or 0.0972 grams). That makes the accepted range for a newly minted silver Roosevelt dime to be 2.403 to 2.597 grams.   |

That info is confirmed from the other official source I posted from 1947 above that uses the 38.58 grains which I had converted to 2.499942g (2.5g rounded up) and a minimum of 37.08 grains = 2.402744grams. (2.403 rounded) if you want the actual figures. If silviosi finds something on the 2.527 from the mint report at some point we can look into that further, or until so perhaps just ignore that particular chart vs the others. Edited by datadragon

I am far from my database and reports to see. I have to do 7 Km to have antenna and pay 2$ a min. I come because this topic is fascinating.
By my mind recall was an 6 year end, Was 1936 or 1946 when the congress give the parameters at the Mint suggestion? In that bill was the min and max of the Dimes. Was hard time for US and they approve that the coins has max and min. and this in order not to affect to much the vending machines.
In 2 and 1/2 weeks I will be back and I can put the data out.
Thanks for yours patience.

. There is no rush. If you happen to find anything different than what has been posted, such as the 2.527 grams used in that one chart and that is from an official source then feel free to post to add to the info. At the moment the two official documents so far use 38.58 grains which is just under 2.5grams (2.499942g) which you can double check the conversion (and rounds up to 2.5grams). |

In fact, it rounds up to 2.500 grams.
