Not a harsh comment at all. It is true.. Do not clean your coins. Do you want us to help you with our numismatic knowledge or do you want to continue defying us in all of our comments?
Cleaning coins is bad. Dont think i can get it much more simple than that. At least they are face value or close to it to begin with, and not a 1916 quarter.
The key thing is not using any abrasive on the coins. Soaking crud off will not hurt, but using a cloth to wipe does due to the micro scratches left on the metal. To prove my point, buy a cheap modern proof coin and just run a cloth over it and you will see hairline scratches.
I didn't say anything and I yes do. All I said was harsh words. I didnt use acetone or salt and white vinegar. I used Irish spring hand soap and water. To get the dirt and whatever was on the pennies and dried it with a cloth not paper towel or a hard cloth.
All said and done just with soap and water can I use that carefully and can I get a thumbs up on these.
Here's a good question. If you certain you have a error and its it'll pass as descent grade. How do you tell the difference from people just having the same grade from people that have the error and that grade. Does matter more of it being less coins out there with the grade and error or less with that high grade only and meaning MS RD 65 or above.
The Red Book of United States Coins by Yeoman. To get an error or a variety attributed on a slab you have to pay extra for that service above the grading fee etc. Or, you can just have it attributed and not graded, also for a fee of course. You can see these different areas on the submission form. You keep showing what you believe to be doubling, if it was true hub doubling this would be a variety, NOT an error.
