1MM-001 1974 S Penny (Coppercoins.com Site)

What is your question? I see a mint mark from a broken mint mark punch. Never heard of advanced copper site.

hello hlw1976

i can not tell if it is a RPM. your pictures of the die markers did not help.

after posting your pictures, look at them to ensure you can see the variety and/or die markers.

capturing an event on the coin may require angling the light low and across the coin so it shows a shadow or a high point.

if a coin has a MINTMARK, a good diagnostic for any variety is the position of the mintmark in relationship to the date ... SO, it is always nice to have a close up of the full date with mintmark.

And thank you levelsofmadness I can clearly see the s is separated at the top corner

I think both your coin and 1MM-001 have a broken mintmark punch with that notch on the upper right serif.

However, what makes 1MM-001 a RPM is the repunching to the south. I don't see that on your coin.
