Well, it's not moiré from the glass.

It seems to be a scanning artefact introduced by the scanner. But you say it
doesn't happen with scans of images on plain or matte paper.
try putting a black card over the postcard before you lower the lid. Also
check your scanner settings.

If that doesn't work, you could try photographing the glossy postcard with a
camera. With some fridge magnets you could stick it vertically to the side
of something metallic in good light, like your refrigerator or your car.
Then crop out or clone out the magnets from the photograph.
