Coinstar DIME reject.......... (with Pics plus weird detail)

AskRaq

......... DANG - no silver!! 1977-D... Oh well, thought I'd share my silly coin & silly questions anyway!

Okay, it's pretty worn... so I'm guessing it was rejected for weight?

No reverse pics, because there is nothing of note on the reverse (normal overall wear with the rims pretty much gone) - but the obverse was interesting...

From about 12-2 o'clock is some metal that has been displaced?? Or lifted up, or pushed over??

But I don't understand how the "bump" occurred in the middle? Is this slot wear?? It looks like the side of the face was sheared off, but the "bump" seems to be smooth'ish, not really raised and definitely not indented? Nothing on the reverse to account for it either.... just a curiosity to me. Any ideas?

And yes, I'm bored..............

I found a similar piece once, although I believe the one I found didn't even have a rim. It's not wear. I forget what exactly the cause is, but it has to do with the coin being machined (ground) down or pressed flat---i.e. post mint damage. Not 100% sure though.

Perhaps it has something to do with it being drilled and plugged with solder or the such - giving it a different weight?

Okay, so I got out my QX3 to take a closer look at the surfaces and see if it would show whether the 'bump' was smooth or raised - and if there was any evidence of sanding/machining... I'm no expert, but it doesn't appear to be ground down, and it appears to have a kind of donut shaped raised area... but I did find this neat detail in the metal at 60x in the center area..... (shown in the bottom left corner of the "detail" images)... the dime picture has a blue & a red box showing the approximate area of the detail pics.










Hmmmm....?

Maybe it's some kind of worm or infection?

You really do have too much time on your hands

Looks like a piece I once saw that had gotten caught in the water pump of a washing machine....pounded all to hellll....

Probably got rejected because it's not "flat" (has the protrusion,center of bust).Also, it has less than standard diameter so is probably underweight and out of acceptable range for the machine to accept it.

I know what this is;
It's a light-strike/calibrating strike.
As you can see, the edge and devices are not "struck-up".
This is a fairly rare item, as most probably never leave the mint and only a handful would be produced at a time before properly calibrating the strike.
The reason you will see more of these as dimes then anything else is that the dime die is the most fragile of them all. If you use too much pressure, you will destroy your dies and/or not be able to use them at their full potential.
I own one of these and dug-up this old image of it...

I believe I have one as well. Now I'm really curious. I need to see if I can't dig it out of wherever it's hiding.

Does it only show on the obverse? And how does it effect the reverse?

LostSisler

It does show on both sides.
I'll find it and weigh it sometime this week to verify that it was not struck on a foreign planchet.

Thanks, I would appreciate that!

Wow a thread with no potential ended up being educational.

Cool

I looked through my handful of random dimes to find a "comparison coin" to weigh..... had no other 70's dimes, so I weighed the three 1980's dimes that I had. They all show normal wear & the edges are not worn smooth on any of them. (Found 2 70's & added them)

1980-D: 2.29 grams
1980-P: 2.29 grams
1980-P: 2.24 grams

1978- : 2.29 grams
1977-D (SHOWN ABOVE): 2.16 grams
1970-D: 2.24 grams
