If you're a collector of anything, you have a favorite. I have a favorites in several categories but with my small soda collection my favorite is the center pictured slug platted squat "JAs Gallagher-PHILADa" It has a graphite pontil and has only manufacturing flaws, to be expected, in a beautiful emerald green. What's your favorite soda? If not a soda, perhaps some other category of bottle.. Remember, it can only be THE favorite.
