possible missing variation on this 5 bahts coin

I'd like to get an opinion from people who are more used to this than me before attempting or requesting an edit to the page.

On this 5 bahts page, it says the 1977 version (๒๕๒๐) has a larger Garuda with larger tails than the 1979 version (๒๕๒๒).

N#3839

However, I think I have two 1979 versions here (๒๕๒๒) and it seems the one on the right has more squiggly thinner tail bits, and the Garuda is maybe a bit smaller.

So I guess the variations are not entirely year-based like indicated? I don't think I'm misreading the date for the 1977 one has a clearly separate last character (similar to a o).

What do you think?
 

Hello,

you can message a referee: @Sakrificed or send a request directly on a page.

there is nothing admin would need to intervene with.

I see that the left one is more circulated, and angle of photo may affect the vision.

If you can find multiple samples with clear difference then the varieties can be accepted.

Personally, I prefer to have at least 3 sample pieces of each varieties is needed before I add a vaiety year line to the catalog.

It's indeed not extremely clear from the pictures but the differences really don't seem due to wear, when you seem them with your eyes. I'll try to make better macro pictures. And if I find more specimens around, I'll add them to the thread.
