Help for price!

I have some bottles of whiskey which I would like to know the price, if possible.
Ballantine, 30 years
Teaninich, Limited edition, 23 years, distilled 1973
Royal Lochnagar, Limited edition, 23 years, distilled 1973
Friar John Cor Quincentenary, Limited edition, 12 years, distilled 1984.

I also have a bottle of Napoleon in Limited edition, for which I have no idea where to turn. Do you have any suggestions?

Thanking

Does that help?
