Re: Johnny Walker blue label
There are three different bottlings of Johnny Blue that I know about. The typical bottling has really gone down in price. In the US, you can find it as low as $120 but $150 is more typical. Typically this would be purchased to drink and not to collect so the box shouldn't have that great an influence. However, people will want to pay less than what they can get it at for retail.
However, there is a George V release that sells for around $500 as well as a cask strength bottling in a crystal decanter and presentation box. This retails for $2600-3500. Presentation box will have a greater influence in what you can get for these two.
