Welcome. Folks use these as postage because you can purchased mint, unused stamp like these at less then face value. But the real value is that they stimulate interest in stamp collecting as your post proves. Do you think that you might enjoy collecting stamps? Don
Thanks don I was wondering why someone would use so many stamps. I've got a small collection but probably not going to get into it. I've got a coin collection to maintain! But again thanks for the info!
