Here is a backward S and normal S pair, both fresh from the vines today.

There are two small open bubbles at the base of the normal S as well as two small annealing cracks in the threads. It also has a faint Amber streak in the dome. It is also the "no underline under o" variety.

The backward S is about as good as it can get, maybe a couple little nibbles, but quite inconsequential.

I'm asking 25 dollars for the pair, and that will include the cost of shipping in the US. As always, I include the finest St. Louis dirt, spider webs, soot, burned building, crack smoke, and gun powder residue for free.
