1960 Vintage Port

[Neail]

I have a case of 1960 Vintage Port. I know nothing about wines. The label reads: Registered Brand "Pocas Junior" Oporto, Alcohol 20% by volume, 1960 Vintage Port, Produced, Bottled & Shipped by Manoel D. Pocas Junior, L., Oporto-Portugal, Imported by Federated Distributors, Inc., Chicago, Illinois. It has been stored in the dark with half the bottles cork up and the other half cork down. (I'm told that matters). I plan on getting rid of it - is there any value left?
