Coinbuf

To damaged to be able to say, copper is very mailable so it may very well just be some metal displaced from the mm, in any case the coin is to damaged to be able to attribute even if it were an RPM.

Appears to be MD from that limited view.

It is a petite head sm letters large cent that has had a very hard life from my limited knowledge of large cents.

Sad I always hate to see old holders destroyed, a real shame. 14 business days so far if my math is right, were these economy?

A perfectly valid reason in my book, nice buy.

Yes I'll take two please.

Also welcome to the boards, if you just set the coins into a baking soda solution and did not rub the coins with the slurry you may be ok. But if you did use the baking soda and your fingers to rub the surface it is very likely that you have done some damage to the surfaces. That slurry is just like sandpaper to the surface of a coin and you may have hairlined it. If you can post a few photos (clear in focus closeups) was may be able to see if there are signs of damage.

Not at all, much better than what is on most of the coinage today.

The only thing that die marker (if it really is one) (and if you can find another 1993-d dime with the same marker) will tell you is that more than one coin was coined from that obv die. And if you are able to find another dime with that marker and its not the same matte finish then you will know yours was altered after it left the mint. Sounds like a lifetime search for the proverbial needle in a haystack, good luck.

So you got out of coins what was that in the 60's or so according to you, but your now an expert on what current graders think.

Don't take it personally, as noted above we see this question almost every day and my comment was not directed to you per say but we are people and do vent now and again. Let us know when you are able to get a weight.

The American dream, getting rich while watching Rocky and Bullwinkle on the couch while waiting for free collage. Well the current dream anyway.

Looks like a large date to me but clear in focus photos and a weight are needed.

What process did they use to determine that it is gold?

Is it not true that in days past they used to eat the hog after the shadow business?

The best grade to collect is the one that you find pleasing to the eye. If that metric fails and you need a financial measure then the best grade is the grade where the next grade up is a large price jump. The problem with that is the big price jump will be different for every series, every date in a series, and then for each mint for every date in a series. As an example a P mint 19XX might be $250 in MS64 and $1500 in MS65; however that same 19XX from the D mint might be $250 in MS62 and $1500 in MS63. If you have a very fat wallet (or you decide to collect at much lower grade levels) you certainly can just pick a grade and buy all the coins in a series at that grade. All of this changes depending on the series you are going to collect as many 19th and 20th century coins are (except for a few key dates) affordable for many up to even MS65 levels. Where many18th century coins can be expensive at low grades even as low as very good grade level. So what you decide to collect may very well decide for you what grade is the best. Most collectors that build date and mint mark sets tend to have mismatched grades throughout the series, usually with the early and key dates being lower grades than the less expensive common dates. Two ways around this is to collect by type, and/or collect moderns where most are priced about the same regardless of which mint produced the coin.

Ditto Edited to add; if you bought this in even the past five years for $20 odds are very high its hotter than the fourth of July, or counterfeit.

Unfortunately as that is not a recognized overdate/VAM I suspect that NGC will grade and holder it as a 1900-O with no mention of the S. You would need to send it to be authenticated and once you have done that process then you could have it regraded in a new holder as a discovery coin. I have never done that authentication process but I'm sure its long and not without some cost. As a side note you might want to look into a third party insurance company like Ship and insure as you have a large number of coins to send in it could save you some money, worth a look anyway.

That's because there is no such thing as a 1900 O/S

It comes down to personal preference, there are pros and cons to sending them all or just a few at a time. By sending them all at once you are spreading the fixed costs of shipping (both ways) and handling fees over a larger number of coins which reduces the per coin cost of submission. However there is greater risk of loss if your one package is lost or stolen in transit, the old having all your eggs in one basket. Not trying to worry or scare you but every now and then packages have gone missing so while the chances are minimal it is a real risk. Its really up to you to decide which way is better and more comfortable for you. One tip is that if your sending them all be sure you only send by registered mail (assuming your sending via the USPS), it is the safest and most secure method the USPS offers. Honestly registered is the only way I ship as it lessens the risks, takes longer than priority but I feel better with the added safety. As you have sent in one group I would wait and see how these grade, in other words use these as a test to see how your expected grades compare to the grades NGC assigns. You can then decide if your ready to go all in or reevaluate the idea. At any rate best of luck with your current submission as well as any future submissions.

Looks like a vise job but I'm far from an expert on errors.

If there is a problem with the value in the opinion of NGC they will contact you and discuss options. When sending in I always use the price I paid as that is the only amount the USPS and/or any third party insurer will pay you in case of loss. If your concern is that it will grade higher (making the value of the coin higher) then the tier you have selected pay close attention to your submission and once grades are posted you can contact customer service and have the value of the shipment adjusted for the return shipping insurance. In reality that does happen but far less than most hope for. If you are really concerned and have not sent the coins you can contact customer service and walk through your form to help you get it correct before you send it.

I do not know as I have never tried to remove solder from a gold coin, however, you can let the coin soak in pure acetone (not your wife's nail polish remover) and see if it will lift. The acetone is safe and will not react with or alter the gold coin in any way, that is the only safe/neutral method that I would attempt. If you have no success with that a trip to NCS for them to evaluate and perform any other possible actions would be the next step.

No, while I don't think so it did cross my mind.

If its real then I would think a repunched date would be more likely than a DDO.
