I assume these two pair of patches are earlier Akro Agate plus another

Patches can be boring but I find these to be a bit above your average.

I think they are old even though they show no wear and tear.

There are 5 marbles here. 2 pair are alike with orange and yellow patches. I can see thin flow lines in the translucent patches that I think are much cooler than your ordinary opaque on opaque base patch.

 

Another two look like identical twins, with a red translucent base and yellow patch that kind of radiates out in lines into the red.

Another single newcomer that I picked up today has an almost perfect round patch of this same red on a opaque white base. Looks like the first pair in color but the pattern looks a bit different?

With the exception of the last big image—which I cannot see enough of—Master imho.    
Five different need to be five different—image wise.
Marble—On!!

I made it smaller, (last one) the other side is just solid white, nothing to see here.

With this type of either Akro or Master Patch you really have to show the seams or cut marks.
Looking from the top does little good except for a few of us here.
We are about learning here--for all that are logged in--no ego involved..
I can tell you that image two--the right hand image shows a "classic" Master Made Marble cut mark--the little u.
The images below it shows a bigger U which usually means Akro but if it is the same marble on the right with the v--it is a Master Made marble.
When trying to differentiate early Akro Patch type’s vs Master Made, all of this info is important and invaluable.

Even with all of the info needed for an ID, the early Akro and Master patches are hard to tell apart sometimes, all color combos are.

Keep them coming and we will do out best here,

Marble--On!!
