J & B Golden Jubilee

Hello !!

I'd like to ask you for some information on a J & B Golden Jubilee bottle. This is a blend of 50 whiskies and is somehow related to the Paddington Corporation (I think they imported the whisky to the U.S.).

I'd like to know if this is a 50 year old whisky blend or just a blend of 50 whiskies with no age statement.
Also I know you do not evaluate whiskies but would like to understand if this is worth 250$ or if that is just a silly number for this item.

Thank you for your time and attention.

David

PS: I sent you a pic. The bottle in question is the one on the right.
