How much is an unopened bottle of coronation ale Fordeham's 1937?

This particular item could be considered priceless. That being the case, itt's only worth as much as someone is willing to pay for it. There are some who'd pay thousands for it, while others might not appreciate what you have at all. I would suggest contacting Dominion Brewing Company. Fordeham and Dominion merged in 2007. Look them up on google.
