Suspicious dime found in morning coffee change- Coin Talk Puzzler Brainstorm

This is a picture of a dime that was given to me by the girl at the corner dunkin doughnut place this morning.




I really can't tell what happened to it. At first glance I thought this might be a satin finish coin put into circulation by mistake. Then I figured what are the odds of that happening. Slim right.....

So my second guess was that someone whizzed this coin, for some *extremely perplexing reason* and then just decided to use it as change. I can't find even a hint of luster familiar & common to 2015P dimes on this weird coin.

That leaves me to this moment in time.

An appeal to this community to solve this riddle... What possibilities could have lead to the conditions observed on this coin?

Looks like a normal dime to me.

 

I guess to put it in perspective here is a regular dime I just found in my desk taken under the exact same conditions as the photo above:

The one on the left is the kind I just spend if I get an opportunity. The other one is strange, and I do look at quite a few of these especially in pocket change.

 

Environmental Damage.. Maybe Dunkin Coffee stain

 

The thing that gets me the most is how uniform the coin is. The torch is close to being FT worthy, the front has no visible wear other than a complete lack of luster. If it were dropped in coffee, it must have been immersed for awhile. I assume, Paddy, that you are referring to the acidity level of coffee, just eating away at the surface level of the coin, much in the same way that dipping a coin would remove a thin layer of the coin's surface metal.

I know this issue isn't that important, just a oddity found that I am at a complete loss for explaining. I'll likely spend it and won't see another one like it ever again.. I'm kinda a dime freak at tines, and never saw one with this kind of surface. It's almost alien. Perhaps the pics don't do it justice.

Please submit any and all suppositions, even if they involve alien abduction theories....

It's been a weird day overall here, and Im ready to expel the weirdness through a pure exhaustion of its strange power to vex us persons who walk through life with vigilance and awareness that make every day a completely new experience.

If I'm completely honest, some days are just "routine", but I like to think that I can reach a higher level of awareness, conscienceness, and understanding each and every day.

 

Looks to be a worn Die Strike. Common appearance on Dimes

 

Here are dimes in my pocket. Notice the variation amongst all of them.

Why limit your thinking to immersed in coffee? What about skin oil which varies amongst people? Smoky environments. Long Sunlight exposure, water, beer, etc

Think about different cities and the air quality? For instance if you are next to a oil/gasoline plant they'll be sulphur junk in the air. Think of any SILVER in that environment.

Why do you wash your car, clothes, dishes, hands?
Are your hand always pristine when you handle coins?

If you job during the day was changing car oil, how would your hands be while handling money?

 

I agree with the worn dies. The reverse looks like it might have radial flow lines toward the rims. I can't tell but I'm wondering if they are on the obverse as well.

I think the color is just due to environmental toning. Maybe the worn dies and toning give it the satiny appearance.

You may also want to check the copper core along the edge. Is it bright and copper colored, or dull/toned/stained? If it is discolored, then it's probably environmental exposure. If it's bright and shiny like a normal MS clad coin, then maybe it requires further thought.

Just my opinion and some things to consider

 

Excellent solutions to getting to the real truth of the matter. I guess we kinds all look at these things in the same way... To narrow the possibilities down, rather than list all possibilities that could have occurred.

In retrospect at days end, today was just a normal day for most people, I regularly interact with, not strange. Its like I forgot to shave with "Occum's Razor" before leaving the house today. Happens to the best of us, I suppose. I blame this Chicago wintery weather and not being able to feel spring yet like in past years.

Thanks to you guys for taking the time to reply to this post. It was a excercize to perform a task that has many possibilities. But all in all I think the worn dies theory is the most plausible. But my favorite was "The Electric Coffee Acid Test"...my name for the procedure my brain used for getting the lustre to disappear by what must have been some very strong java. I thought about staining and wear from regular DD coffee and thought. ..oh! he must be thinking about the ph og the drink. There are those amost my work mates who have said I have a "bulldog mentality".

 

She gave you a picture of a dime?

 

People still use cash?

I have a jar that I've thrown pocket change into since I was a teenager. I don't think that the fill level of the jar has moved for about 5 years. The idea of pocket change is almost becoming a foreign idea to me. Off topic, but that is the first thing that occurred to me when reading the OP.
