I have $700-800 in old stamps that I put on envelopes and packages that I am mailing. I got them at various estate sales, in fact I bought about $40 worth of $.29 stamps a week ago. The problem with selling old stamps on ebay is that many of the very old ones are worth a dollar or so each but who wants to screw around scanning, describing, posting an auction and mailing and then having to pay 20% in fees. It just is not worth the time. I keep them sorted by denomination to make it easier to find them when needed. I will post a picture in a minute after I restart my machine. the mail program is screwed up.
