You have some old some new.  The way they're arranged makes it hard to point out which is which.  

The ones with three narrow ribbons, in three colors equally spaced around the marble, those are modern Asian.

The green on white at about 3 o'clock -- Akro Moss Agate.

The white with a large red patch and smaller green patch near the center -- Akro Tri-Color Agate.
