1992 Quarter With Vertical Lined Background, Specimen?

I think I know what you mean. I was searching through some UNC provincial quarters, and noticed that some of them had a slight SP appearance because of the lined fields. Kind of put it aside and never thought of it again, so I am not really sure why this happened.

Thanks. I guess it's just a very good quarter then.
And the penny isn't, apparently, the lines are going the other way.

What do you mean by 'odd about that penny'?
Anyway, some actual pictures, as requested. My camera couldn't get the lines. In person the lines are the clearest on the left directly below the queen's hair, and directly on the right side of her face.

As you can see it is very nice, you can even see the texture on the earring, necklace and crown. Even her eyeball is still there.

By the way, I noticed that the quarter is missing one and a half denticles, between Elizabeth and 1867. it doesn't look like someone picked it off or something though. The left one is nice and smooth, having only the slightest "bump". The one on the right is like half the size of a normal denticle.

All my coins are found in circulation. I've never bought anything uncirculated or specimen or anything like that.

I wonder, if the penny was cleaned, wouldn't they scratch off the raised parts' details too?
And have any idea about the black dots on the obverse? It's on top of the coin and not in it.

Do any of your quarters have missing denticles? I only have 1 of this kind, so nothing to compare it to.

I just noticed there's a bump on top of the 1 of 1 cent. Looks like a bit of extra metal, do you know what it is?

I'm sorry that these are about the best I can take pictures of. I only have my phone's camera with me now. I wonder if there's anyone I know who has a DSLR and is willing to lend me. Or maybe I can try borrowing a microscope from the science lab. Not sure if that's going to help but who knows? Earliest I can try that is on next Monday though.

I'm probably getting a magnifying glass on Sunday. I saw one at Dollarama last time I went there but the magnification is only 5x while the recommended is 7x. Should I get the magnifying glass anyway?

It's an iPhone 4S. It's good, but it is pretty difficult to focus on near objects.
I'll get the magnifying glass then.

That's actually a bit big and looks kind of expensive for me. I'm living abroad in a small dorm room so I don't think I can make that. Plus it will be hard for me when I have to move.
I just tried with what I have. I used a flashlight and a painting of mine (where the background is grey). I tried photographing a silver quarter but the glare is too bright and the only thing I can see is a white circle.
What I have in my rom are yellow lights. They're not bright either.

Here's the obverse of the quarter


With old batteries in the flashlight


And here's the penny



Actually looks pretty bad.
