Look, here’s what’s going to happen. Some day, you’re going to send that coin in to a grading company and it’s going to come back in a “body bag” with the description “Altered Surfaces”. There will be no more detail than that. No Dremels, no acid, no sandblasting, nothing. Just Altered Surfaces. I suggest you print out this entire thread and file it with your junk coin in the body bag.

Me? I'm going with 250th anniversary and dropping the BS.

What I hope is that the correct party is our hosts, whose personnel I like very much and enjoy doing business with immensely. I can’t say the same of the “P people”, whom I have found aggressive and grouchy, frankly

I underestimate nothing. I have an ANACS account which I refuse to use anymore.

If both TPG's involved are among "the big two", our hosts and the four-letter "word" starting with "P", you have a real conundrum. If either is ANACS or ICG, trust me, they're wrong and the one from the "big two" is right. If neither is among the "big two", your story has wasted my time.

Yes, of course. All it takes is a stout collar, like from an IGC slab insert, or an older NGC one, or even an AirTite gasket or ANY type of gasket, but anyway, your edges are NOT crisp and squared off like a newer or early saved coin should be. They are quite seriously beveled. In short, the "valleys" beween the reeds ARE ERODED, as we would expect. They are not unaffected at all.
 
On edit: I just went back and looked at your edge shots. They very much ARE the same as the two surfaces. Highly eroded. Have a look at how rounded those rims are! This is clearly an acid etched coin.

Arrrrrgh! So much wishcraft, so little study.

As I see you are pretty new here, I can see why you have no idea who Mark Feld is. This is a man that you would rather have on your numismatic side, than to ridicule him. 

Yes, Philadelphia is king. This is widely known in the field of numismatics. Formerly, all Mint management was in Philadelphia, but fairly recently (in coin terms) they were moved to Washington. All mints other than Philadelphia are known as “branch mints”. Only Philly is THE Mint.
 You can find the tools to blow up your font on the above Toolbar. Jeez, do I have to teach everything?
 
By the way, the list of mints that I have personally visited includes Philadelphia, Denver, San Francisco (old), San Francisco (current - outside photos only, they don’t let people in), Carson City, New Orleans, the old Canadian Mint in Ottawa, the Tower Hill Mint in London, England, and the new British Royal Mint in Llantrisant, Wales. I intend to visit the Dahlonega site early next year.
BTW, at the other site where our OP previously pushed his dime, having two account names is a banning offense. They are really inflexible over there on their “rules”. In my opinion, the chief moderator over there is a [nickname for John appended to slang term for the gluteals], but that’s just my opinion.

A few historical points that argue against this coin being what RR2020 says it is:
1) There have been no, repeat no, sandblast coins EVER produced at the Denver Mint. P, S, W? Yes. Denver, no. Denver is a tiny Mint without room for experimentation. They don’t even have a die shop. They BARELY have room for a gift shop.
2) The very first one produced and released is the 1994 nickel (note: NOT a clad coin) in the Jefferson Coin & Currency Set. This is a year AFTER the 1993-D dime here.
3) That 1994 nickel was UNANNOUNCED, completely. No mention of its finish was in the sales literature. The hobby was unaware of it until an article about the special surface was published in Numismatic News. The author of that article was, wait, I’ll look it up, oh yeah, ME!
4) And if all this weren’t enough, the “fact” (as if...) that the reeding is unaffected is irrelevant. I have Matte Finish coins I have made, with a mild acid and an ultrasonic jewelry cleaner, and their edges don’t look to be affected either. 
 
4a) THIS is my acidic solution. It takes about 24 hours to get a finish like the OP’s dime.

5) I shouldn’t have to go to all this bother to prove anything to a newbie troll. Frankly, my word backed by my experience should be enough. 

Ok, I'll give in. Looks like a Matte Dime to me. I would send it in to have it graded!! Your persistence has convinced me that you are far more knowledgeable than anyone else here. 

I won't use my phone's camera for coins. I bought a microscope. VERY low power one. Full stage like a bio one, but far lower magnification.

Reminds me of a joke: Two ships collided last night. One was carrying red dye. The other was carrying purple dye. Both crews are believed to be marooned.

No, it was to prove a point, aka "win a bet"metaphorically. Another numismatist said toning doesn't affect the numerical grade and I said it did. So I sent it in. It did. 2 points worth. Then. Probably 3 today.

On that day in history, Robert E. Lee visited Ulysses S. Grant in the White House, the last time the two would ever meet. Nine days later, the "Golden Spike" was hammered in at Promontory Point. Maybe they needed to cut staff due to subpar sales for commemorative golden spikes. 

I have a '64 Kennedy that I sent into our illustrious hosts that had enough nasty hits on it to grade MS63 at best, but it had wild peripheral toning. It came back MS65. I did it to prove a point, but err, umm, I guess I proved "two points".
 
The "best" part is that the toning continues to develop new colors in the NGC slab. Heck, it's probably a 66 now.

That is why you should never run up stairs with scissors. You could fall, break your neck, and put your eye out, all at the same time

One of two universal injuries for young boys, along with “you’ll break your neck”. I used to plug nickels at 50 feet with a .22 caliber Anschutz target rifle.
Note to newbies: if you run across late 1960’s nickels with nasty dents in ‘em, yeah, it was me.

Chicken dinnah!

Darned airplanes. It's all their fault.
