Mint marks

[lineop3]

I can't locate these rpm mm on CC. Can I get some help in locating them?

I don't think those are RPM's which is why you're unable to find them on CC.

Oh. It looks like the "push" style mm. Thanks Rock for clearing that up for me.
I think I need my eyes checked. LOL.

I am kind of curious as to what a 'push' style MM is, or what you have learned this to be. I am unaware of anything or any conversation of this type.

[lineop3]

I don't remember where I read that but it's the rotated mark (cw) I was thinking about. Sorry.

[mustbebob]

Oh...OK Aisha. I only asked because I had never heard the term before.

Sometimes, Bob, I see mintmarks that looked like they have been pushed on by something, like these do. But that would have to be "post pushed on". (?)

Sometimes Bill, mintmarks like this suffer from machine doubling that has worn over time. Other times, it may be a legitimate rotated or tiled RPM that has just worn as well. If they look like this though, I'm afraid there is mot much that can be done to accurately attribute them.
