I'm also a stamp collector and i'm sure those that collected at one time remember soaking stamps in water to get them off the paper. Well with todays newer stamps that are self adhesive, they are known to be impossible to remove from the paper and were made this way so they could not be removed and reused. I've never tried this with cards but a three dollar can of Pure Citrus Orange Air Freshener Spray found at Walmart works wonders on newer stamps. It naturally evaporates on stamps and only a couple sprays are needed to wet the stamp and paper. It would probably need a few more sprays on a card but might be worth a try. After a few days the orange smell is gone too. Use the spray outside because its very strong smelling and keep it away from plastics like PSA and SGC holders. Also, if the tape comes off but a little bit of sticky glue is left behind, just rub baby powder on the card till its not sticky anymore.
