1987-P Broadstruck Dime

I came across a 1987-P dime with what looks like a broadstruck reverse, the obverse is fine, anyone have an idea about this or its worth?

I am not sure what the name of that error, Cool find!

That one's more than PMD. It's LOL.

 

Yes the reverse did not leave the mint like that. Someone did that intentionally after it left the mint.

 

When I saw the dime I was thinking "design creep" as @mikediamond calls it.
Also called a flared die face. I am still not sure though.

 

I once had one as well and since tossed it as PMD.

 

Neither am I, but it sure doesn't look like it was the result of PMD. You can still make out the legend - UNITED STATES OF AMERICA and ONE DIME. Cool find!

Could an "Obverse Capped Die" produce a coin with this effect.

 

No. There are no marks on the obverse of a Dime which look like that. Those lines have to come from somewhere, and if you don't see them on a die, they didn't originate at the Mint.

And keep in mind, a broadstrike by definition happens in the absence of a collar, so if there's a rim you're not seeing a broadstrike.

 

The OP's coin does not look like a "Broadstrike" assuming the Obverse and Reverse photos are of the same coin. What I was contemplating was the possiblity of the coin bring struck between the two dies, then sticking to the top hammer die, and then being struck down onto another planchet which may be the cause of the splaying of the design on the reverse.
I believe the marking on the reverse of the OP's coin could have only been produced in a high pressure press. No¿

 

I started to wonder if this was a Brockage.
After looking on www.error-ref.com
It seems like it is most possible to be a counterbrockage.

 

it is the same dime in the scan, obverse and reverse, at first I thought someone did this, but I think it came from the mint like that, you can see the letters stretched to the rim.

 

I thought so too when I first saw it, but after a closer look, I think it did come from the mint that way

 

At first I thought it was PMD. But, I do believe this came from the mint this way. It took awhile looking at the pic to see that those are not ridges, but, design elements. I think the minimum clearance for the dies was decreased causing excess pressure on the anvil die. Thus, making the design elements squeeze out from under the die. There may have even been a shift of the anvil die causing the center devices to become deformed.

 

Can you post the pics again so they are full images? When you upload a file next to the pic in the file it shows two buttons. Click on the button that says full image.

 

Coins don't leave the mint that way. If they did there would be a whole new category of errors with photo examples.

(Me again)- 99% of the time someone thinks they have an error coin, but it's not.
I have a few error coins I got in circulation. A nice struck through grease on a 2004 nickel. And a couple of misaligned die strikes.

 

If you go to http://www.error-ref.com/ most of the errors listed do not have photos.
Which make it hard to verify some errors. Some errors are one of a kind!
When I posted an error coin of mine 6 members told me it was not an error, they all were wrong. A Mr Mike Diamond made the last post on that thread.
I am not certain how the OP's coin got the damage to the reverse side, as I have yet to find a website that show every kind of error made. I am really certain that it is not PMD, as it would be next to imposible to create that kind of distortion to the reverse without some type of damage to the obverse outside of it still being set in a die. So hang in there John, and stick to what you believe.

 

If you do enough research there are photos for everything.
1 site is not broad enough research.
There are many other sources besides the internet.

 

Please list links to any error site you are privy to. I would surly be thankful, as well as many others. after all that is what this site is all about. Thank you Michael.
