I have some EDWARD VII gold coins from 1905 - 1910.
The official specification for that coins is:
Diameter :22.05 mm
thickness: 1.52 mm
Weight: 7.98 gram
My question is if this specification is really supposed to be accurate because some of my coins are with diameter with above 22.20 mm and the thickness is less than 1.52 (~1.45 mm). The weight is indeed 7.98 gram in all of them.
Is that mean that my coins are not origins?
Thanks!
