Variants for Chinese cash coins

I was wondering whether the different variants of the Chinese cash coins had to be added in here. For one cash coin, especially in the Sung dynasty, the emperor would have many different calligraphy style of the same writing.

Take for example the Sheng-sung tung-pao coin.
It is written in three fonts.

This would be a huge undertaking as there are so many variants of the coins. Uploading all of them would cause the amount of cash coins in the database to increase exponentially. Since not many people bother about it here, would it be a waste of time for me to upload all variants in writing?

what's the difference between these two coins?
https://en.numista.com/catalogue/pieces19758.html does not say Diameter  
https://en.numista.com/catalogue/pieces7996.html says Diameter   21 mm
I have two coins of these,
-one 22mm/3.55g
-one 23mm/3.75g

It's the same.

Oh wow I never noticed!

I don't think there is any difference. Maybe I should have that checked. I'm currently working on UK and I will shortly return to China.

To Fliegendehollander:

All variants are different, and should therefore be different articles. Although they have the same emperor or era, they have different fonts and would be listed as different types.

It would not be a waste of time and I appreciate it that you do this work. Thank you!
