Hello Luis,

What you have is not a Mint Error. It is damaged. Someone somehow removed the Reverse by scratching it off.

We call it PMD - Post Mint Damage

The clues are as following -
1. The lines on the surface which look like scratches
2. There is a missing Upraised Rim like on the Obverse. Both sides should have an upraised Rim.
3. It is impossible to have a Blank Reverse with a perfect Obverse since both sides need equal pressure to have the images appear.

Peace

 

yup, PMD

 

Another fact from wikipaddia98

 

Not impossible, but the blank reverse won't be uniformly flat either.

 

It appears to be a human created error.

 

So.. That wouldn't be an actual error.
It's just a human made damaged Cent.

 

Welcome to CT, Luis! Keep looking, learning, looking, learning...you get the picture.

Luis, welcome to CT...this is a Penny...what you have is a Lincoln cent.

 

Makes us all want to collect pennys.

 

That Penny is Choice B.U,
and Full Red !

 

Lol

 

Thanks everybody1

 

Luis, Do not discard this coin. I have a 1940 penny with no mint mark struck only on the face which has been in my posession since the 50s and I can say with a high degree of certainty that it has never been modified. 2 easy explainations; lower die half installed upside down or double layer of material went thru the die.

 

First, welcome to the neighborhood, Larry!

Some people may call me a skeptic, and some of them may be right! I'd like to see photos of your one-sided penny. Also, please explain how the anvil die can be installed upside-down when both ends are not the same diameter.

 

That's the only penny I'd absolutely love to put in my mouth.

 

Luis was last seen on CoinTalk November 2020.
I bet your Cent is also altered.

 

A few things to consider;

1) The die CANNOT be installed upside down. Installing a die upside is the equivalent screwing in a light bulb upside down. Can't happen. Look at the attached pic from coin week and it becomes obvious.



2) While I suppose it's not impossible for 2 planchets to enter the striking chamber and stay perfectly aligned and the top one doesn't get hung up on the collar, I would think the probability of such an occurrence is very, very low. Even if it did occur, that doesn't explain the numerous heavy scratches. Take a look at some blank planchet errors. NONE have heavy scratches because they can't occur in the blanking or upset mill processes.

The coin in the OP had the reverse ground off after it left the mint. It's not worth hanging onto, since it couldn't occur at the mint. I would recommend taking some time to study and learn the minting process. It will make it much easier to determine true errors and varieties from damaged/altered coins

The reverse has been ground off. How thick is it? Take pix and post them showing the thickness of the coin.

 

Authentic cent with one side...
