Xenia, Ohio. Bank of Xenia. Post Note. ND (18xx). $5. PCGS Choice About New 55. HPC. Proof.,Wolka 2889-07Var. A rare proof to begin with but especially desirable as a sub-variety with the obligation of twelve months instead of the usual thirty months. Unlisted in both Harris and Wolka. This is the only one we have ever seen and it is presumed to be unique. PCGS Comments: "Mounting Remnants on Back; Minor Stains". In light of rarity and grade these are of no consequence.
