Depending upon the years/types of stamps/covers/plates/stationary/etc. some stamps can be well worth taking the time for someone to appraise them. If they've been from your grandfather there is lots of potential. A good "start" would be to go to one of the local stamp shows - The next big one is SPRINGPEX 2015 STAMP SHOW; SATURDAY MARCH 7th 10am - 6pm; SUNDAY MARCH 8th 11am - 4:30pm

Take a sample of what you have and there will certainly be someone who will be willing to take a quick look and let you know what you have - At least there you'll have 20-30 vendors who have good knowledge and can point you in the right direction.
