I won this dime today on ebay. I'm almost sure it's struck on a planchet punched from quarter stock. Weight is 2.943 grams. The photos are the sellers. What do you think?    ANA ID: 3203813 - CONECA ID: N-5637 Clean a coin that may be worth collecting? Please DON'T! When in doubt, leave it dirty!!

I think you're right. I've seen many other dimes of this year with the same error. It's similar to the 70-D quarters struck on dime stock planchets.

Hmmm...I don't know. A quarter is 5.67 grams. And the dime is supposed to be around 2.27 grams. It does appear to have a fat rim though. Pretty much, I have no idea, but I'm curious to see what everyone else thinks.  |

It's one of the better-known dates for dimes struck on quarter stock. Still not a common error, though.

@Yokozuna, Could you take a picture of this dime edge-by-edge (like in the third picture) to a quarter? That might solve this mystery.

Cool coin! Was that error advertised on the ebay auction, or did you just luck into that coin? |

As always, THANKS for the information, Mike. I've learned a lot about errors by reading your column and the replies to both my error post and many others on CCF.

?
What are we looking at here ?
In the 3rd pic. I see two coins.
Which one is the OP's ? If any.
I'm assuming quarter stock is a lot thicker
than dime stock. Correct ?
What is the actual thickness of the OP's dime ?
Would the stock used for both dimes and quarters
be of the same composition ?

How could a quarter fit into the device if it's meant to fit a dime? Wouldn't the planchet have to be smaller than the denomination being srtuck such as a penny struck on a dime planchet?

If it had been punched with the correct quarter size punch of 24.30 millimeters, it couldn't. The error here is that the mint punched the dime planchets out of the flat clad sheet that should have been used for quarters. So it's not an off metal error, it's an incorrect metal stock error. The planchet was the correct 17.90 millimeters to fit in the dime collar, but the quarter stock that was used was too thick.

@SteveCaruso- I don't have the coin yet. I hope to have it by next week. I'll do a 3 coin shot when I get it so we can see the regular dime, this dime and a regular quarter all in the same shot. @Lobby- It was an ebay item listed as "Off Weight Planchet." I thought it must have been quarter stock that was used for the planchet when I saw the side-by-side third shot. I hadn't seen one before, so I REALLY wanted to win this coin. I'd been watching the auction for days just waiting for right time to try and grab it. I had to bid 3 times in the last 7 seconds of the auction and won the coin with only 1 second left. @Indian1- The 2 coins in the third photo are a regular dime and this dime. A clad dime is 1.35mm (+/-10%) thick and a clad quarter is 1.75mm (+/-10%) and both are the same composition. I'll have to check this dime when I get it, but my bet will be it's at least 1.75mm. I also did the following calculations to compare the weight vs thickness: Weight 2.943 grams on the error dime divided by the normal dime weight of 2.27 grams equals 1.2964. Thickness of metal stock. Quarter stock is 1.75 millimeters divided by dime stock of 1.35 millimeters equals 1.2962. That's why I'm sure it was quarter stock used in error to make a dime planchet.

Definitely possible. A dime struck on proper thickness clad stock should weigh 3.07 grams. If the stock is a hair thin a weight of 2.97 grams is believable. (Low tolerance for a clad quarter is 5.45 grams and a dime planchet punched from stock thin enough to produce a low tolerance quarter would weigh 2.95 grams.)

Math time!
quarter specs 5.670g, 24.26mm diameter, 1.75mm thick
dime specs 2.268g, 17.91mm diameter, 1.35mm thick
Let's say you have good calipers handy, you can quickly check if it's quarter thickness, but what if you don't?
pies are square, but coins are round:
Quar: 3.1416*12.13*12.13=462.245mm² surface area
Dime: 3.1416*8.955*8.955=251.93mm² surface area
So if it's quarter thickness stock, it should weigh 251.93/426.245462.245 as much as a quarter = 3.351g3.090g
2.943g is nowhere near that (4.8% light).
Doncha just hate when you reverse numbers?
