Lightning can strike twice! Another tough Seated Liberty half for my set - 1857-S
Thanks to @hbarbee for the heads up for this one, a nice PCGS XF-40 with a Hansen pedigree holder. The look of this coin matches the others in my registry set. It does have some subtle coloring when tilted into the light. Amazing that it can takes years and years to find suitable look keys for your set and boom! Two of them within a week!
