Glenlivet Golf Course Series from the 1980's

I have attached a photo of the three tins that I own. St. Andrews, Muirfield and Turnberry. I oringally thought that three tins made up the set, I am now finding out that six tins make up the set. The other three being Carnoustie, Royal Dornach and Royal Troon. Is this correct? Am I correct in saying that they were introduced in the early 1980's. And if this is correct, what year were they put out? Were they done over one year peroid or two, three? These have been stored away in my closet. Any info would be apprecitaed.
I have also been trying to determine their value. Any suggestions other than e-bay. The Glenlivet that once was inside is only a memory.
Thanks
