This 1968D dime weighed less than a 1943,1962,1963,1964,1967,and a 1970 dime. It appears to be copper but is much lighter in weight. It's "rough" to the touch. Appears to have rotated and been stamped more than once on reverse. Any ideas ? This picture also shows a 1964 and 1964D Dime which both weigh less than a 1963 Dime. Is this a copper alloy? Thanks  |

I made a "home made scale " using a popsickle stick, etc.
I used the 1943 as the base against a 1963.
The 1964 and 1964D weighed less than the 1963.
The 1967 and 1970 weighed less than the 1964 and 1964D.
The 1968D weighed considerable less than the 1967 and 1970.
Crude way to do it, because I don't have a scale.
Could this 1968D Dime be stamped on an aluminum panamanian planchet ?
Thanks

The U.S. Mint does make coinage for other countries...it's always possible for a foreign planchet to find it's way into the hopper.

Not being able to see what we think is impossible doesn't mean it's not true. It just means that we haven't seen it yet.

From the color, it looks like it has spent some time in the dirt. Chemicals in the dirt will change the color of the coin. If in moist, acid soil, it can also eat away some of the metal, resulting in a slightly lighter weight. Exact weight and a closer photo will help determine if this is what happened.

Your two quotes are in conflict with each other since copper and aluminum look nothing alike  I also looked at the Numismaster.com database from Krause and I did not see any Panamanian aluminum coins from the mid-late 1960s. Quote:

That is because the 1964 coins are silver(2.5 grams) while the 1967 and 1970 coins are cupronickel alloy(2.27 grams). A balance beam is very limited in the information it will provide. Coins have a manufacturing tolerance, typically +/-0.1 grams, while wear and environmental damage can further reduce the weight of a coin. If the brown coin is the 1968D, the likeliest explanation is environmental exposure from being on the ground or buried. Dark grey-brown is very common for CuNi coinage exposed to soil. |

Let me try to explain better:
1. Scale was set so a 1963 and 1943 dime were balanced,or weighed the same. Therefore, silver dime to silver dime.
2. The 1964 and 1964D weighed less than the 1963, thereby indicating a possible copper alloy. There's a "die crack" through "IN" with a line toward the chin. If they were silver, they should weigh the same.
3. The 1967 and 1970 weighed less than the 1964's. I agree, they're alloys and should weigh less.
4. Now the 1968D. It weighed considerable less than all of the coins, thereby indicating a possible aluminum combination.
The "Weights" are listed as follows from heaviest to lightest:
1. 1963
2. 1964 & 1964D
3. 1967 & 1970
4. 1968D
I know there has to be a "tolerable allowance" but the differences are quite contrast.
There is reported a 1970 Aluminum dime on a Philippine planchet.
Now the color of the 1968D Dime: It's a " dark rose " color under the scope. It has an obverse die breakthru of the leaves and stems on the forehead. The reverese shows strong doubling on all letters and the torch seems to have been stamped three times with rotations to the east on each strike.
I'm trying my best to get a digital photo as soon as I can. I'm totally disabled and it's hard for me to get out. I've been collecting coins for over 50 years and this is a very unusual coin that I want everybody to see.
I'll appreciate any additional comments or information.
Thanks Have A Great Holiday !

Check out some USB microscopes for taking pics of your coins. You can just plug it right into your computer and they take great pics.
