Springbank

I have several dozen bottles of Single Malt Scotches I received in a trade a few years ago. In it was a couple bottles of a Scotch called Springbank. Someone then told me that they could no longer import Springbank into the US or Canada. They also said that these 2 bottles may be 2 of only 12 in the US. I thought that was kind of strange, but here I am.

Is that the truth?

I don't drink Scotch at all and have no idea if the bottles I have are worth anything or if they are just high priced mouthwash. Some of the labels I remember are Edroudar, Bowmare and a whole bunch of Glensomethings.

I am curious about the Springbank however.
