Started collecting "cancelled" stamps back in 1975. My mother thought it would be a great hobby for me to stay out of her hair. It worked. I had to give up collecting for 35 years, but started it up again over the past few months. I collect everything as long as it's used. I want my stamps to have actually gone somewhere! I adore sorting, tracking, learning about each stamp, the whole shebang. I do keep track of what my stamps are worth, but it's not my reason for collecting.
