That is part of the charm Jim, the way it is treated in the mail. Ilford postcard stock is RC paper so it holds up better. I found the pearl coat further protects it. The glossy tends to get scratched in the mail. Besides it is so much fun getting all the postcards. I usually send out more than I receive.
I might be persuaded to part with a couple of my precious boxes of postcard stock for a good deal on a future lens?
