differenze moneta 2 Drachmes (new lettering) 1982-1986

Buongiorno,
mi è stata regalata una 2 Drachmes (new lettering) 1982-1986 in cui riscontro le seguenti difformità:
Diametro e spessore differenti rilevati con il calibro.
Materiale visivamente differente, anche se non ho le conoscenze e la capacità di determinare la composizione.
Diametro della moneta standard 24 mm
diametro della moneta scura 23,8 mm
spessore della moneta standard 1,6 mm
spessore della moneta scura 1,8mm
Mi trovo di fronte ad un falso, anche se non sembrerebbe, o a qualche prova non classificata o ancora le differenze rientrano nella normalità?
Grazie in anticipo a chi vorrà e potrà rispondere.

Your pictures have an awful low pixel definition. What are the dates of your coins ?

​The date is "1982" and the weight is correct.

Being in Maillechort, this coin can get different color than the standard Ochre, that still doesn't explain the difference in diameter. You might test if coins are both non-magnetic.

Quote: "Frenchlover"The coin is not magnetic. I think (sope) that by mistake a rod of different material/composition was used, at least for some coins, and the difference in thickness and circumference is due to the different expansion / shrinkage of the material after processing.
