Learning about RPMs, are these rpms and why or why not?

I'm having difficulty identifying Repunched mintmarks.
I thought these two coins would be an example if someone can help me out a little bit.
If these are just normal coins or what causes the s to look like that.
Thank you in advance.

The first two are 1972 and the second two are 1973, they are shinies. Not proofs. Pretty sure, no proof like cameo.

Welcome to Coin Talk
This site explains how the RPM happens: http://www.error-ref.com/?s=repunched+mint+mark
The next 2 sites list RPMs, DDO, DDR, etc.
1) http://www.varietyvista.com/
2) https://doubleddie.com/
There's more online help and several books on the subject of error coins. I think the sites I listed are an excellent start. Happy hunting

 

All mint marks were hand punched pre-1989 and more chance of a RPM occurring as the link @thomas mozzillo has provided .

 

Full photos of obv. and rev. please.

 

Almost looks like a small die chip inside the MM, just IMO.

Is it possible that the mint mark punch they used to punch the die was worn out?

 

Sorry it's been a long day I will post photos later when I'm able to I appreciate the information already I didnt know mint marks were hand punched at one point

 

I don't think any of those are RPMs. Best way to familiarize yourself with what RPMs look like is to browse the VarietyVista website, and look through the listings. Start with 1972 and 1973 but also look at other years. Once you look at what is listed you'll see that yours are not RPMs, and what you should be looking for:

http://www.varietyvista.com/02b LC RPMs Vol 2/RPMs 1973S.htm

 

Sorry for the delay

 

Thank you, that's what I was looking at and my brain gave out. I appreciate all of the info

 

Photos posted thank you!
