Rare Error?

[Jonathan]

I found this 1987 D in my pocket change hoard that has backwards letters from the reverse stamped over IN GOD WE TRUST on the obverse along with the UNIT backwards along the left edge with the I stamped through LIB of LIBERTY and there's part of the corner of the steps and other features like a mirrored image on the obverse over Lincoln's head. I read online that this could be an extremely rare flip error where the coin didn't eject from the anvil die and flipped over landing misaligned and upside down getting struck again by the hammer die either with or without a planchet on top of it. Any information is appreciated especially if it is valuable and what I should do to go about having it certified and graded? I am attaching photos however for some reason they were downgraded and are not as clear as the originals. Thanks

First off, welcome to the forum.

An image of both sides is important 99% of the time. Please add a reverse image and a closeup of any of the extra letters.
Are the letters that are backward on the obverse of the coin raised or incuse (recessed)? I can't really tell from the images.

If they are raised you may have something but if they are incuse it is most likely what we call a vise job. Someone puts two coins together in a vise and squeezes. This is considered PSD (Post Strike Damage) and not valuable except as a learning tool. They grab our attention when they get as strong as yours.

The Memorial building and letters are backwards and incuse, which means the damage was done by another coin

Commonly known as a "vise job". Another coin was pressed into the coin. Not an error.

I appreciate all the help I can get. I'm not a collector, I have been saving pocket change for about 45 years and only recently learned about errors being valuable so I am going through the thousands of Lincoln cents to see what I might find. I have a pile of 1984's and some definitely have the doubled ear but I am having a hard time of identifying the doubled ear some of the time. Perhaps I should create a new post on '84's and what is the best/easiest way to identify the doubled ear. I have a lot to learn and with thousands of coins I need to learn quickly.

The most important thing I can think to tell you is to sort through all of your coins and separate them out by year and mintmark then read about what is possible to be found for each pile then search.

Secondly, keep those coins [and keep them separated] then as you find out about other possible errors/varieties, re-search them. I have found many that I didn't know about the first time through.

Good luck and keep us posted on what you find.

And yes, definitely start a new thread for each coin, you'll avoid a lot of confusion. Good luck !
