I'm not very experienced in coin collecting so I have a some questions that I would like to ask. Up until now most of what I know about coins comes from the red book or sometimes other places, recently I decided that it was time to start learning a bit more and find a forum to join which is how I ended up on CT. So I would like to ask some questions about storage, grading and cleaning. I'll start with storage, so far I mostly store the coins I have (which are mostly from the 60s and up) in small bags or in a small plastic drawer and sometimes in rolls. Though my wheat cents I had in a small bag but I ran out of room so I put some of them in a ww2 canteen cup. so is there anything I should improve? I was thinking about getting something to put some of the nicer coins separate so they wouldn't be loose being knocked around with the other coins. Any ideas? And are these holders any good? the next thing to ask, is there anything that I could do for a coin like this? and also what could I do for coins with gunk stuck to them like this? also how do you tell when a coin has been cleaned? Part of the reason I'm asking I because years ago when I was younger I had a few wheat cents that I cleaned with i think baking soda and vinegar and a tooth brush. I don't remember which coins I did except this one. so can you tell it's cleaned and how?
For grading I'm just trying to get a good grasp on what different grades look like. So i have some coins I have taken pictures of and guessed what the grade is, so I would like some opinions on whether I'm correct or off the mark. G-4? F-12? Vf-35? G-4 or vg-8?
I just happened to run across your post from one minute ago so this will likely be the fastest reply you'll ever get. As for storage, it really depends on the condition as to how much it matters. The newer and more luster you're trying to preserve, the more important storage becomes. You'll find products like Intercept Shield that are made to clean the air around the coin while it's stored, but have a service life of 10 years. Need to keep humidity down. An attic isn't a good storage place if trying to preserve originality. Nor a can in the ground. If well circulated copper, just make sure they're not in old pvc pages or flips. For those cents if there's a nicer, rarer date, maybe you want to use a cardboard 2x2 or plastic 2x2 for some and the rest can just go in plastic tubes made for them. Would keep them neater, take up less space and basically seal them from the air. I have a pile of them in a small box. For the corroded cent, looks like a 1910, it's too corroded to save. You may as well turn it into the bank. Same with the 1970-S. No saving and not rare. It would go in my cash in pile. Cleaned coins usually have several tells. Can be one or several combined. Usually on coppers, the color can be off. That 1937 the color is way off. They become a peach color. Also fine scratches or swirls across the surfaces. On silver, a uniformly dull flash across the surface without cartwheel luster when tipping the coin, would indicate it was cleaned at some point in it's life. If a coin is well worn but very shiny it's been cleaned or polished. Being well worn it should no longer be shiny but people clean them to try to make a worn coin more attractive. In the old days cleaning used to be acceptable so a good portion of what was saved did get cleaned and was ok at that time. Eventually that belief changed and did a complete 180 within the hobby. Not as much got through those times unscathed so now original surfaces are highly desired. Many coins have been dipped in a chemical to clean off ugly toning but if handled properly those can still be considered uncleaned. Anything wiped harshly with anything becomes a cleaned coin now and the grading companies will not straight grade it.
The last pictures have scratches and pits. They would not straight grade and would be considered a Details grade only. Check out PCGS photograde. There you'll find illustrations of anything you want showing the progression through grades of any type.
