Hi there! Whisky.com can date your bottles if you like, but not value them. For a value, you can try McTears.com or Bonhams.com. However, keep in mind that this is a common brand, still in production today. What that means is that it's not likely your bottles are going to hold any significant value.
If you would like a date - please post a photo of one of the bottles. Be sure to include front, back label, closure and a bottle shot. If you need help with posting pictures, please let me know.
