Not an expert collector but in my capacity as a non-expert, I say leave it alone! That tiny spot is not worth worrying about and won't affect the grade. Your 1922 shows excessive hairlines. If you did that, stop doing it! Just being frank.
First, the 1922 is a common date in just about any condition. Just not worth your time to remove those spots. Even in MS-60 it’s a $35 coin, maybe, I say maybe $60 in MS-64. Second, the 1924, is AU at best and that’s a $40 coin. That little carbon spot isn’t going to make a big difference in price. Not sure if it’s an S mint as no reverse photo but that’s only a few dollars more.
Yep, I know. I usually sidetrack from the Captain Obvious stuff when I can, and break up the monotony. The same blahblahs has been asked ad nauseum to a level of watching air move, in the 17 years or so I have been on CoinTalk. So, I do what I can. I appreciate you efforts to correct me, though. I realize it was in good faith and not a lookatmegetim reply. Your welcome. (What...you expected a humble embarrassing apology for what you may perceive as a Faux Pas? Not from this Grump...I have been married to HER for 54 years).
The 22 had a old cleaning, which is one of the reasons why I picked that one to be a guinea pig. The carbon damage alone makes it uncollectable for anything but stacking. Even 50 years ago, people apparently were trying to shine up their coins.
The 24 up top is not. I have not touched it. I didn't even want to take it out of the Saflip to photograph it, but I did after all the comments. The following two probably have been in the past. I didn't rub them at all. MS 70 can be applied without any pressure. Obviously rubbing is not part of acetone dipping nor is Ezest.
Electrolysis did not fix the carbon spots on the bottom two coins in the photo. They are dead soldiers worth melt value plus whatever the normal coin premium that is usually associated with US coinage. RIP Lady Liberties.
I'm not seeing it. I've got several MS65 graded coins. There are always a stray hairline or two in in higher grades. The photos are the best I can do.
One more, mouth facing up to capture the field left of the head. This is as about as far as I can zoom out with current stand.
That camera is made for VAM searches. It works great for that. The original full coin photos are as good as it's going to get with existing equipment.
Yes, it was very common. After grandpa gave us his coins the first thing we did was use silver and copper polish on a few of them. Fortunately we didn't touch any of the high value ones. Coins were no different than silverware. Make it shiny! You can take good pictures with a cellphone. I don't know if you want any tips, but put them in natural light, like on a windowsill out of direct sun, and experiment. On my phones I've found that zooming in like 30% and having the phone farther away gets the focus sweet spot. Crop the image afterwards. I don't know what you have but you should be able to get more natural looking images.
It's got awesome luster. It's just my photography skills are severely lacking. I found it's twin sister this morning going through more coins, same date and mint mark, but not as blemish free as the one posted, but still a high grader. Peace dollars are hard to judge because their strikes were so weak. I don't know how much that plays into a TPG opinion or if they take that into account.
Your assumption that I have a smart phone, while admirable, is wrong, I still like a flip phone, lol I am NOT a phone person, and my laptop follows me where ever I go.
"carbon spots" on silver are not carbon but chemical reactions with sulfur compounds and except for pinpoint size should be left alone unless you are a chemist. (IMO).
Pickin.........I have a decent camera for micro shots. I didn't find anything under Dinelite. Am I stupid? I want one to take a full image of both sides of a silver dollar, with decent lighting. My 4.3 screen microscope will not get a full image of a silver dollar. It does a good job on the minutia, just not a full coin shot. I am not finding anything on the web for such a tool. ???
