I swapped some of my
inherited stamps, when I was young, with a friend for these stamps.



and some more similar stamps.
These stamps are supposedly from uninhabited islands like Staffa, Davaar, Eynhallow in Scotland. Some quick searches on the internet showed that some stamps were issued for the tourists to these islands in the 1970s and they were charged double the ordinary price.
Does anybody else have stamps from these small islands. And are they worth anything, now that these small islands do not produce stamps anymore.
