2.38 and 2.39 grams would be consistent with silver Roosies worn to the G-4 range.

Been wondering if any circulation wear is or is not in play myself. Thanks, Doug. Yes, one of my thoughts as well. I mentioned "Wear might be the answer for the difference which photos would help." in earlier post which could explain the small variance below the different weight minimums. There are rolled thin planchets and of course foreign planchets etc but this is just below the tolerances. The book he said mentioned 1951 D+S can be thin and I have never looked into that before either. A coin struck on a planchet punched out of stock that was rolled too thin on the rolling mill is called a rolled thin planchet but as an example, a 1974 quarter was struck on a rolled-thin planchet. It weighs 4.92 grams instead of the normal 5.67 grams (non silver normal weight 5.67) just for some more info as these do have value so might be worth looking. Maybe can look for any rolled thin planchet 1951 D+S in heritage archive for a comparison or anything of value related to a foreign or off metal planchet error for that year https://varietyerrors.com/wrong-pla...price-guide/Quote:
Sil & Data, good info. Would you happen to have an original source we can reference?
I don't know the source of 2.527 from that document vs 2.5 as typically mentioned in others. The official document from the treasury from 1947 (mentioned at the bottom) the last document was taken from in grains when converted is 2.499942g (2.5g rounded) so that may be an official source so far. Thats another thing someone can look for if desired as mentioned. Edited by datadragon

This is from an article in SDBullion: Quote:"The U.S. first began minting dimes in 1796 following the Coinage Act of 1792. In the original piece of legislation, the dime was called a "disme." The first dime was issued at a weight of 2.70 grams (0.095 ounces) and was composed of 89.25% silver and 10.75% copper. These Draped Bust dimes kept this weight and metallic content until 1809. From 1809 to 1837, the U.S. minted the Capped Bust dime, which weighed 2.41 grams (0.085 ounces). From 1837 to 1891, the Seated Liberty dime was minted, although the weight changed twice during that time. The metallic composition was changed to 90% silver and10% copper, and the weight changed to 2.67 grams (0.094 ounces). Between 1853 and 1855, the weight was reduced to 2.49 grams (0.087 ounces) due to rising silver prices. The Coinage Act of 1873 changed the weight to 2.50 grams (0.088 grams), where it stayed until the Coinage Act of 1965." Agree that 2.38 g is minimally below tolerance for a 1951 Rosie, but consistent with circulation wear. Edited by Zurie

@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.
