Thank you Glenn and wrt. I don't have any 'first day covers' or postmarks on any stamps on the date of issue, until I reach the modern stamps, my mother added to the collection. I haven't left the 1800's to see what she collected, yet.

My 219D is the closet to the day of first issue, of the 'classics', I have. I admit to being happy to see some of these stamps postmarked the year they were issued, worthless monetary wise, as they may be. It's still neat, to me, to see a stamp that was not only issued a hundred years ago, but see the postmarks as old as they.
I will look into that site, Glenn. Thank you.
wrt, Scott Catalog, I don't know why I didn't look there. Newbie mind blank. I'm so 'into' looking at what I have, I'm not
looking at what I have.
