Zusammenfassung:	The present disclosure relates to a coated article with low-E coating having low visible transmission which may be used in IG window units for grey appearance. An exemplary embodiment relates to a coated article including a coating supported by a glass substrate, wherein the coating comprises the following layers in the subsequent order from top to bottom: a dielectric layer (24) comprising silicon nitride; a contact layer (21) comprising NiCr, a first IR reflecting layer (19) comprising silver; another layer comprising NiCr (17); another layer comprising silicon nitride (14); another layer comprising NiCr (11); a second IR reflecting layer comprising silver (9). The second IR reflecting layer is at least 50 angstroms thicker than the first IR reflecting layer.
