Zach RiceThree of the Cobbs you posted are from the E98 set, E94, and E93 set.
You are missing the E98 Cobb in green and orange. You are missing the E94 Cobb in red, blue, green, and purple. Also, it is possible that Cobb's E94 card exists with an orange background. This is a priting variation though and shouldn't be considered one of the standard colors E94s come with, in my opinion.
