If you submit itfor grading now, it would receive a "details" grade, indicating it is genuine but damaged in addition to normal wear. I can tell it has been cleaned just by looking at it. NCS (part of NGC) offers a coin "conservation" service, which is a professional cleaning, that may have done some good for this dug up coin. However, I submit that it is now forever damaged. The rule of thumb in numismatics is never to clean a coin. There are *rare* exceptions, and it takes a *lot* of experience to know what those exceptions are and *how* to clean a coin without ruining its numismatic value. Secondly, your eBay posting is dishonest. You cleaned the coin, therefore you KNOW the coin is cleaned, and you are morally obligated to advertise it as a cleaned coin. You may be new to numismatics, but that is no excuse for dishonesty. Change it. Now.
Yes, I'm quoting myself. I wanted to make sure you read and understand this part of my post. Read it again. Oh, and as a cleaned coin, you should probably price that around $50.
Because I found this in the ground all I did was use water and lightly touch it with a q-tip...That's it...I don't feel I'm being dishonest...but numerous people told me that is not going to damage it...and I'll just have it graded to make everyone comfortable...I'm again being honest I did not clean the coin....I came on here for advice not to be dishonest....
And it's gone: "This listing was ended by the seller because the item is no longer available." - what happened?
Probably decided to re-write the description and cut the price, a smart thing to do, under the circumstances.
Looks like cleaning did not really hurt it... https://www.cointalk.com/threads/out-come-on-my-1921-standing-liberty.268822/
