After the death of Jean-Jaques Dessalines in 1806, Haiti ended up getting split between two states, one in the north under the leadership of Henri Christophe, and one in the south under Alexandre Petion, until the country was reunited in 1820 under Petion's successor Jean-Pierre Boyer.
Currently, the Numista catalogue includes coins from the northern and southern regimes of this divided period in with all other Haitian coins, but I think they should be separated out into their own issuers, since they were their own countries separate from each other, and actually used separate currency standards, the north using something based off the old French livre and the south having a decimalized currency. It makes it a bit confusing to have them mixed together with other Haitian coins.
Example of a North Haiti Coin: N#38028
Example of a South Haiti Coin: N#28714
