Whisky.com can possibly have this bottle dated, but not valued. If you would like it dated, either post a closer and clear photo of the coat of arms near the top of the label (or let me know if it refers to "Her Majesty the Queen" or "His Majesty the (late?) King." Also, let me know if you're able to see any numbers on the back of the front label or if there are any numbers on the bottom right of the front label.
For a value, try McTears.com or Bonhams.com
