Hi
Have tried deep-edging the image using the path tool.
I find that using that tool works best when removing a backround in an image.
It takes a few minutes, though if you have many stamp-scans with the same
dimensiona nd edges that single path you spent an hour creating becomes a joy

You can try "Color to Alpha" using a background color not found on the
