By default Numismatic Overhaul changes villager trades as well as modded ones that use fabrics villager trades system but unfortunately VillagersPlus doesn't do that. This datapack just changes those emerald trades to the Silver Coins from Numismatic Overhaul, the same as it changes the other emerald trades.
This datapack also adds the Supplementaries - VillagerPlus compatibility datapack by default so you wouldn't need to download the other compat that includes it.
It does not include Promenade - VillagerPlus Compat but I can include it if requested.
