I have seen some Haitian coin uses the Grego-Julian calender and others use the Haitian-Republican calender.
Some of the coins with the republican calender, is dated by the Grego-Julian calender (which is also featured són at least some of them) and maybe the Republican date in the comment section.
I think for some sort of consistency, the coins which features the Republican calender should be the main one. Since at the time I assume the Republican calender was the main/official calender at the time, and guidelines say to use the official one.
If that's the case, the following coins need to be changed:
I think I got 99% of the coins in question. Thanks ;D
