1945 S Wheat Penny - Possible Defect On Reverse

@rahz, first welcome to CCF. Second, yes uploading pics to this site takes a little bit of practice, although the tutorial helps. Finally, I see what you are talking about with the letter O in ONE; however, that looks to me more like a well-placed hit from circulation. It is a little more clear when you blow up just that letter:

I agree with Spence and frog above, what you have is a coin that the reverse took a good hit on the O in one from circulation.. Interesting to learn, but in the end it's just post mint damage ( PMD).

to the CCF!

Scopes are nice, but they are tricky to use for photographs. Many here use their microscopes for locating errors, but cameras in phones for photos. Photograph your coins while laying them on a hard, flat surface, and hold your camera directly overhead. Try using daylight as your lighting source, or some other diffused single light source. The best advice to give you is for you to practice, practice practice. There is a large section here within the pages of CCF dealing with coin photography, if you're interested.
