Yellow red and brownish green??

And this one too...?

The first one is a Peltier “Rainbo” imho. It is a nice Rainbo to be sure
The second one looks bigger and I will throw out a possibility of it being a Ravenswood if it is under or ¾”. Bear in mind that I suck at WVS ID’s.
The third one is a nice, well filled“Slag”Imho, probably an Akro.
All opinions are needed here and most welcomed.
Marble—On!!

Woe

Well, that one is not too hard.

It does look like it was "polished". The hard sharp lines on the holes reveal this to me, also the dull finish.

Still a nice marble.

"Electric Yellow" CAC--love it!!

Here are two that show actual wear patterns that are close to yours in appearance. Notice the little scratches and the overall wear that may be called “pocket wear” by many sellers.
The original surface still shows through however.
I treat CAC marbles like Antique hand-made’s and no not mind a bit of wear or imperfections.
I stop at anyone polishing any machine made marbles—I just do not want to ever board this ship.
Still a nicer marble that you have—unless it was misrepresented—if it was--- go after the seller for a refund.
Marble—On!!

I agree the CAC has been worked on.
