Hi Joshua, Thank you for contacting Mearto with your appraisal inquiry. I can find a few bottles of this vintage available for purchase online for about $40, so it would be unlikely to sell for much more at auction. Based on the photos and information provided, and subject to examination, this is: A vintage sealed bottle of 1976 Brotherhood Winery NYS Port limited production, numbered 1064 of just 2496 bottles made 750 ml With dust and possible cellar accumulation, unopened. PROVENANCE: inherited $40-50* *represents a fair-market value for auction purposes; retail or asking price may vary. Please let us know if you have additional items to appraise, and thank you again for using Mearto.
