The Numista listing for the liard of Liege 1745-1746 KM# 150 used an incorrect photo until the beginning of 2023.
It is likely that many members listed their coin as KM#150 because of this error, when it should be listed as KM#146, which has the date on the side with the 5 small shields: N#22120
Check your coin to see that it is properly attributed.
