Not really although someone might give you a small premium if they collect these.
Minor greasers are just too common to  be worth much over face value.

I'm gettin better! 😊
Glad to see that you are willing to learn and not just rely on everyone else to do the work for you. This hobby is a lot more fun when you can identify some of the many forms of damage and errors for yourself. Keep on replying to the different questions, it is a good way to teach yourself. State what you thing the right answer is, if your right, great, if your wrong, (and don't worry about being wrong, everyone is once in a while) you will learn the correct answer for the next time.

That is Die Deterioration Doubling caused by a worn die. Value 1 cent.

If the fingerprint is fresh, an acetone soaking would probably remove it. If it has been on there for awhile,there is nothing that can be done.

Thanks for the article Greg.
At least you know you have a one of a kind error. Good find.

It is not flawed, it has been intentionally routed out by someone possibly to be used in jewellry. There is a member of another forum who custom makes these coins to be used in bracelets.

Mike Diamond is the senior editor & author of the error- ref.com website so if anyone can figure out what is going on with your coin, it would be him. Personally I have no explanation.

Both those coins were graded by what is known as a "basement slabber", not one of the recognised TPG's so you can't put too much trust in the grades. 
Unless both those coins would grade a high MS, it would cost way more to grade than what they are worth.
 
 

What you have is a WAM with Die Deterioration.l
Certainly not worth sending in as there is nothing to authenticate

Wow
That has been heavily cleaned. Must have used SOS.

Just a damaged quarter. It is impossible for another number to appear during the striking of the coin.

I just checked all ten of your previous posts and I don’t see where you posted an error coin.
Please explain what coin you enquired about.

See your other post

Looks like it may be a Nickel blank that has some damage.
