I had found a small stack of antique postcards in my garage I had forgot I had. Some look as old as the turn of the century. (1900s)
Where can I go to try to date them since alot of them are not dated or used with a postal mark to know.
I can guess where most of them are from though.
Any help would be appreciated. I would like to sell them, but have no idea what old post cards are worth generally.
Thanks!
