Diameter?
For a silver planchet to weigh that little, it would have to be TINY.
A half dime?
Foreign coin sorry
Netherlands East Indies 1/10 Gulden. Struck at Philadelphia in 1941 and 1945, San Francisco in 1941, 1942, and 1945. 1.25 Grams, 15mm.
I have several half dimes in my reference collection that are at that weight (1.24 grams) or even less, but presumably not when struck; the reduced weight is due to circulation wear. The specified weight (mass) for United States half dimes was 1.35 grams for the Flowing Hair and Draped Bust designs, 1.34 grams for the Capped Bust and Liberty Seated half dimes, but was reduced to 1.24 grams for the 1853 - 1855 half dimes. Perhaps, as stated by Dorkgirl, what you have is a Liberty Seated half dime planchet?
Good ID!
Can you post a picture?
Forgot to say 86.5% silver
Forgot to add 86.5% silver
The NEI 1/10 G is .720. I will keep looking.
Would be around 1944 era
The Venezuelan 1/4 Bolivar was struck at Philadelphia in 1944-46 among other years. 1.25g, 20mm, .835 fine. Very close to your specifications.
The $1 gold piece is around 1.6g I believe and even that is tiny. 1.24 silver must be itty bitty.
I have been through Altz & Berton's Foreign Coins Struck at United States Mints and the Standard Catalog of World Coins 1901-2000. Altz & Berton state that the Venezuelan 1/4 Bolivar was struck at Denver in 1944 while the Standard Catalog indicates they were struck at Philly. I have to think that your piece was struck at Denver on one of these planchets. If the fineness is off by a few percent, well, there was a war going on.
I hope I said this correctly:
You are trying to compare apples to oranges.
A cubic inch of gold will weigh 10.13 Troy ounces.
A cubic inch of silver will weigh 5.53 Troy ounces.
If you had a disk of gold and a disk of silver and both were the same diameter and same thickness and same purity, the gold disk would be much heavier than the silver disk.
If the thickness and the purity were the same, the diameter of the silver disc would have to be much larger than the gold disc in order for the weights to be the same.
Just eyeballing gold and silver for comparison is likely to lead to erroneous conclusions.
The 1904 Panama 2-1/2 Centesimos "Pill" is 1.25 grams of .900 Ag, struck at Philadelphia. Your reported .865 fineness is damn close to the standard for the above.

3CS are 14mm, 0.80g (0.750) from 1851-1853 and .75g (0.900) from 1854-1873.
Not relevant to OP's ? but to the discussion of small silver planchets upstream.

If it was struck at a U.S. Mint, it is no longer a planchet. Perhaps you should change the thread title to "manufactured"?
