Anyone know how to tell the difference between copper and gold OPC glossy for series 2

They all look like gold to me compared to series 1 which hard darker for the copper. Maybe I just have no copper yet. Any help appreciated.

Very hard to tell, almost impossible through scan or if you dont have another to compare to. I only noticed when I happened to pull one and was sorting with my other coppers.

It is easier to tell from the back.

Copper is more brownish, Gold is a little more metallic ( I think, mine all went to COMC so I dont 100% remember of have them in hand )

Thanks. I just know series 1 was easy to tell. These series 2 all seem lighter to me.
