The bottle you have is a 1982 Family Malt collection which was bottled for the Spanish market, I think in around 1999, although I can’t quite make out the date on the photo. This is no longer available on the market so I’m not sure what its current value would be.
You could try contacting one of the specialist auction sites such as McTears
www.mctears.com or Scotch Whisky Auctions
