Yes and no, currently no because the spot price of gold is at all-time highs coins that have issues or are impaired in some way (like ex jewelry coins) are selling for the same prices as unimpaired coins that grade in the AU range.   Your coin would have to grade in MS64 or better to rise above the current spot gold price which today was around $2,162 per ounce.   The only real difference is it can be easier to sell an unimpaired coin to a coin collector who may not want such an impaired coin.   Most dealers would sell this for spot + 5%, they would buy it at spot - 5%.
Yes if, and this is a big if, in the future should the spot price of gold retreat, that is when you could see a difference in value for your ex jewelry coin vs an unimpaired AU coin.

No, strike doubling only.

Not for me, I looked into it when it was launched but have never become a member and have no plans to.   I truly dislike the format of the site, and so far it's mostly just a big photo sharing platform.   The few times I looked at any of the chat areas most were being bombarded by internet only vest pocket type dealers, turned me off right away.

@Coinbuf then my bad I didn’t know it started that far back … I’m behind catching up as usual I thought it was last week or so when they started that ….

@Sandon please post any dealer or bullion operation that is selling impaired AU dets quarter eagles for $260, I would love to load up at that price as that would be significantly under spot.   The term "a rising tide lifts all boats" is in full effect with the rising spot price, I'm not sure that you could even buy half a coin at $260 today.

I use a digital microscope that plugs into my computer to image coins (also not the best images) and can't give you advice on how to use a smartphone, but some of the other forum members may be able to help you. (You might want to post future topics on the Newbie Coin Collecting Questions forum.) The photos of your 1925-D quarter eagle are too small and too grainy to see much detail. I was unable to enlarge them much and really can't see much about the coin. (It wouldn't be possible to definitely authenticate or grade the coin from even the best photos.)
   For comparison, here are (1) photos that I took of a genuine 1925-D quarter eagle graded MS 62 (Uncirculated) by PCGS and (2) photos taken professionally by Stacks Bowers, a major numismatic auction house, of a genuine 1911 quarter eagle graded MS 63 (Choice Uncirculated) by NGC.




   An "ex-jewelry" or otherwise impaired coin is undesirable to collectors and would sell at a discount, perhaps a substantial one from a coin in otherwise equivalent grade. I respectfully disagree with @Coinbuf about your coin because the gold value of a quarter eagle is currently around $260, while an unimpaired AU 1925-D lists over $500.

Your coin appears to have significant die deterioration, the anomaly you see is related to that and not an RPM.

You can read Kurt's short and colorful reason he is no longer a national volunteer for yourself.
 

There isn't any such thing as "toning error", just simple exposure to the elements.

Beautiful coin Joe. 

Just quick cell phone pics.  Bought this for the Hallmark holder more than the coin, but I do like the coin as well.

The only thing it could be is a strike through, but from your photos it looks more like a scratch to me.

And then il post results of my next submissions to maybe you can see how it’s done. 

Sorry it is just a damaged coin.

I see only worthless minor strike doubling.

Your decision to crack these out seems not a good one from your photos.   Granted photos don't always tell the full story, but just from photos I see your chances of anything over PF67 as remote.  In hand I might have a different opinion. 
You would have been better off submitting to PCGS for crossover at the current grade or perhaps one grade less.  NGC doesn't offer the crossover option except for PCGS graded coins.
I am unclear what motivated you to crack these from the PCI holders, but my opinion is you just lost a lot of value. 
In the future if you want a coin in NGC or PCGS plastic is is better to buy the coin already in that plastic unless you are an expert grader.

The MAC sticker has been around for many years now especially prevalent on ebay, however, that sticker service is a joke (imo).   MAC stickers are the sticker equivalent to the self or basement slabber, it means nothing to knowledgeable collectors.   That doesn't mean that MAC does not have followers, I have no doubt that there are some buyers that look for MAC stickered coins.   Last I knew the MAC service is not a service provided to the general collecting population like CAC or the new CMQ are, it is an in-house sticker that one seller puts on his own inventory, it should be easy to see what a conflict of interest that would be.   Because the company that puts MAC stickers on slabs has been around so long you will see these MAC stickered coins from many sellers.
Another big problem with the MAC stickers is the marketing garbage they do.   If you have not seen some many of their stickers will say ridiculous things like 4FS or 90% FBL for full bell lines.   Clearly 4 full steps on a Jefferson nickel means nothing just as almost full bell lines on a Franklen half, but MAC markets these almost there designations as premium coins due to almost making the cut.   What they are doing is not illegal hence why they are still in business, and if you can buy a coin with one of their stickers at the same price as one without that is fine.   But most knowledgeable collectors know that the MAC sticker is worthless, sadly there are lots of uneducated buyers in the coin marketplace.
I have also been told that one of the principal owners of the firm behind the MAC sticker is the same fellow that owned and operated the now defunct ACG (Accugrade) grading service, Alan Hager.    I don't know if you are familiar with that individual or his grading company, but he was offering grading and slabbing services which started in 1984, two years before NGC or PCGS.   The problem with his grading service was the same as the MAC sticker, he was grading his own inventory and often gave inflated grades and/or straight grades to coins in his inventory with issues.   ACG ended up in court with several lawsuits which shut the company down.
 

It's certainly plated. As for the rest of what you say here, it doesn't even demonstrate notable critical thinking efforts. I can think of no reason anyone would bother to lead you in the right direction after that.

As you probably know, these coins were minted on planchets that were made of zinc- coated steel. Zinc and steel both oxidize in an unsightly manner, especially after having been in circulation. Many thousands of these coins were stripped of their zinc coating and replated by aftermarketers to make them appear shiny. Their feeling was that this would make the coins easier to sell to the general public. They were often sold in three coins sets, one from each mint. They were often found in souvenir shops and mail order catalogs. The reprocessing of these coins removes any numismatic value they may have. That's why you were told your coin is only worth face value. Your coin was likely plated several years before the elderly woman obtained it.
There is an easy way to tell if your coin has been plated. Look at the edge. If it's smooth like the surface of the coin, it has been plated. if there is a dull look too it, it's original, but has obviously been polished. Either way, its numismatic value has been removed. It's only worth one cent.
It might not be a bad idea to do a bit of research on these before you reject advice from knowledgeable collectors.

I don't trust a word the OP has to say. He has shown that to me. 

Poor choice of words.
