Re: collectors woes
Well, in Macallan's case, sort of! They bought some really old Macallan bottles from Italy for their distillery own collection only to discover that the contents were of considerably more recent provenance than the bottles and labels (which were probably genuine).
After that their 'replica' series disappeared from the market for some reason. However if the bottles you're referring to have been in your possesion for some time I wouldn't worry.
