Hello, hope you like this block. I always enjoyed geology and so to find these and the others in the 1982 Minerals issue was a delight.

SG 1278  with perf 14½  (not the 12½  perf sadly - which is catalogued at £1 a stamp as compared to 10p for this one)  Always worth checking the perforations, as I often tell you.

Still, it is a nice MUH block I think you will agree;  and if you didn't know, Agate is a banded form of finely-grained, microcrystalline Quartz.  Its name comes from the Achetes River in Sicily where Agates were first found.  

Enjoy your stamps
