The dime size bubble on the back side was a very nice surprise in what I believe is a light yellow green glass cramed fill wth fizz and seed bubbles. Also has a couple short olive stringers. One in the front dome and one in the rear skirt towards mold line. No problem displaying this SN18 between another two and not seeing the numbers. Like looking at the bubbles in these oldies just as much and as long as I keep it between two other SN18s I will not forget it is a 210 SN18.
