Trying to see if the white ones are a swirl structure or two-seamers. In spite of some ambiguity, I'm gonna guess two-seamers.
And with that I say they are modern Marble Kings.
I can't remember if I have any white modern Marble Kings, but I do have pinks. Small ones.
Edit: if the whites are swirly then obviously not MK, but swirly would make them more likely to be Champs.
