counting beads around the rim

https://en.numista.com/catalogue/pieces1073.html
i feel pranked...
I have this coin from 1990 and 1994
I really counted the beads on my coins, and first thought they have both 72 beads. Still, the beads look differently aligned to the letters
then I looked at the other side of the coin, and counted again, and...
one has 72 beads, the other 66
so my 1990 coin has actually 72 beads on the obverse and 66 on the reverse

maybe there should be a "hint" in the description field to only count the reverse then
