Older collectible stamps are still valid at face value. I had some old 32 cent triangular stamps I was saving get ruined with a water spill, but they were still valid postage. (Not saying it's a good deal, but many things on eBay are not.) If anyone outside the country needs US stamps, drop me a mes...
