Luxardo 'Ardo Mintilla' -please help

[Unregistered]

Hi, i have an unopened, fairly old looking bottle of Luxardo's 'Ardo Mintilla' which i want valued. Can anybody help me? I have looked up Luxardo and they do not manufacture this type anymore.
Made in Italy, manufactured in Padova. 0.6L, 27% alc.
It is a circle shaped bottle with a clock in the middle.
Rd. No. 44153

Any ideas?

I feel pretty sure that this is a liqueur rather than a whisky so I doubt that anyone can help, the other is that the site doesn't value bottles. If you need it valued try an auctioneers site, I would have suggested McTears or Christies but they seldom sell liqueurs as there's virtually no market for them
