1989 Penny No Mint Mark, If You'd More Pics Lmk

Hey!! It's a weird crack along the top of America. Die break?
Sorry, I just learned how to reply lol

Not sure really. I guess a description of what kind of anomaly?

Looks like a Ridge Ring to me also.

Here's front and back

Thx for adding the overall pics to this thread. I'm seeing Ridge Ring on the reverse. Click the linked text to learn more.

Almost all odd coins you find in circulation will be post mint damage. Coins spend very little time at the mint being made where relatively few errors can happen. However coins can spend up to a century or more being tossed around and beaten up an almost infinite number of ways when circulating. The concept that every odd looking thing might be a valuable coin error wastes a lot of time for people and gives them a lot of disappointing replies. This relatively new "fad" is due to so many non-error coins being put on ebay and click bait youtube videos. Funny colors, most weird marks, dents, missing letters, splotches, discolorations, etc. are typical of damage and not collectable errors.

MIcroscopes can be the newbies worst enemy b/c the tiny imperfections people see, that have been on coins forever and ignored by the hobby, are so often mistaken as something important.

If you want to know what to look for that the hobby finds interesting and collectable, then get some boxxes of penny rolls from the bank, sort them by date and mint mark, and then use a site like varietyvista.com. They have date by date listings with pictures. Find an EXACT match (all pics for each entry must match) and you have a doubled die, RPM, or OMM. Also, you WILL find doubling on your coins that does not match the pictures at that site because there are forms of non-collectable doubling that occur such as Machine Doubling or Die Deterioration Doubling.

It takes a lot of research and study to sort collectable coins from the huge amount of non-erro, damaged, and inconsequential things that fool so many newbies.

Ridge Ring from a worn die and maybe Split Plating as well.

no mint mark means it was minted in Philadelphia and the feature on the reverse is a Ridge Ring as mentioned.
