Found a fat dime. Opinions please and thank you

Came across a 2011 D mint mark dime it's considerably thicker and the reeding was barely stamped in. Could it be a broad struck? Let me know what you think.

Can you provide us with the weight? Thank you.

 

It's 2.3 grams I have no idea what a dime should be.

 

Your dime was spooned, hammered, tapped

Huh? Ok I can see how something like that could flatten the reeding but (it's hard to tell from the picture) it doesn't look flattened it's more like whatever does the reeding applied almost no pressure. Also how could someone make the coin wider doing that without reducing the diameter of the coin?

 

What are the diameters of the two coins you show in your photos?

 

Just a hair under 18mm I don't have anything that measures in anything smaller than mm and the scale I used only does one decimal point under a gram

 

You should continue your numismatic journey by learning more about how coins are minted.

The reeds are applied by the collar during the strike. It's physically impossible to have a decent amount of design detail without having the collar impress the reeds.

If it was struck outside of the collar (broadstruck), then it would be larger than a normal dime (17.91mm).

 

It is a very early stage spooned/dryer coin. Early enough that the reeds are being flattened (but are still present) but not long enough to have started reducing the diameter.

 

They got tired and gave up.

 

It measured a hair under 18mm so 17.91mm sounds right. Now let's say someone had nothing better to do than beat it with a spoon what I don't get is why it's almost twice as thick as a normal dime.

 

It's not but the rim becomes extra wide. I can see that from your photos.

 

Only the edge gets wide..
Try this.. Take a small hammer and tap a Quarter or a Dime. Easy. All the way around. Turn the coins as you do it. Then you will fully understand!

 

Because it appears so lightly but so evenly done, I do not believe it was spooned. I once tried that with a silver half dollar (back when they still circulated) but found it very hard to keep it even. Besides, a dime would be hard to hold and constantly turn while you struck it. I think it much more likely it spent a little time in a dryer.

 

Incorrect. Not a dryer coin. It is definitely spooned.

 

You are the expert, but I am curious. What is it about the coin that tells you that?

 

Ok I'm including a picture of the fat dime and 2 others with it the rim is the same height off the surface of the coin as the other 2. Now I admit it's been a long time since I took geometry the pyramids we're used as examples (they were being built at the time) but I'm still not understanding how you can increase the thickness without losing diameter. What happened to over all mass. Sorry I have OCD and I really am trying to get what everyone is trying explain to me but what little I remember from school isn't letting it add up in my head. If everyone is tired of trying to get me to understand it's ok I get that a lot.

 

It's hard to see diameter accurately in that picture, although it does look to me slightly smaller than the other two. Could you show a picture of the three coins standing together edgewise on a flat surface? (III) Put the one in question in the center. I suspect that the spooned coin, even slightly spooned, will show its slightly smaller diameter, which should show up if they stand straight up together. With no more spooning than you have there, there won't be a huge difference. You might also put them, on edge and face to face, between hard flat surfaces and should observe that the odd one will roll out while the normal ones won't, even if the difference in diameter is not obvious to the eye. Of course, it would be great if you had a really accurate micrometer.

 

I also suffer from OCD.
You are only tapping the edge. It expands. Its a minute change not enough to really tell the difference. Believe me.. That did not occur during the minting process. I have seen many over 34 years collecting errors and understanding how post mint damage occurs.

 

dryer coin damage is more of a rounded off effect. The spinning will smooth and round the edge into the field. The Dime in question is flat and sharp.
