It is the consensus that Alley didn't make patches. The patches found at the Alley site which excited so many of us are probably Akro.
So that leaves Akro versus Master. When I was looking at your marbles I tried to see the seams. Not all the seams were front and center, but since I already gave you a bit of a hard time on your Wedding Cake question, I tried to get a good feeling for your mossy patches without asking for more pictures. And the feeling I got was that the seams fit the typical Akro pattern more than the typical Master pattern.
