From right to left a .57 Pelt Rainbo.  Middle is it a Pelt PP or a helmet .62/.63 and is a black helmet or yellow if so?  Left .61 weird Pelt or a Vitro?

Pelt Rainbo's @ either end & not positive about the center one, are there any seams ?? 

[marblenewbie]

Don't seem to be any seams as I know them to be.  Just seems to be a yellow patch over half and black over the other half.  Can't even tell which is the base.

The middle one is either Akro or Master imho.
Show us where the yellow meets the black at its most rounded point to be sure. I can see the cutoffs from the top in image #3.
Marble—On!!

Here is where the yellow meets the black.  The funny thing as they are almost exactly equidistant.

Akro Royal or Master Comet.
Aventurine always will not define an Akro Royal vs a Pelt Peerless Patch. 
Royals did show up with it in some. I have a trio in this color combo with it, over the yellow. If there is AV in the black that is noticeable then I would say that it is a really/really weird (to me) Pelt Peerless Patch.
Master Made Patches are usually but not always 1/3 fill to 2/3 fill color to color or matrix to matrix. Cut-lines matters but there are always other things to consider as well. Comets came in Black and Yellow as well—no AV in my experience.
I will commit to this being a killer Akro Royal, and very nice old marble. These came in older 100 count, “Leather look” or “Old book- texture” boxes along with other color combo’s of marbles.
Marble—On!!

Sorry, I answered your explanation yesterday, but I guess it didn't go through.  Thank you for the great analysis!!!  I will put it in my Akro best bin.
