Those look like wavian licensed nato cans so should be the same red anti rust coating inside. I’d trust them. Easiest way to tell if real is the seam weld. If the seam weld is tucked it’s real, if you go to set them down and the seam weld is sitting on the ground they are knock off garbage. Reason being it’s much harder to seam weld the real way wavian cans are made.
