I Need Help Id-Ing My Penny Reds.

OK, I attempted to scan both of the Penny-Reds that came on my Mourning Covers and got no replies. I think because I was asking in the wrong forum? Anyhow, it was mentioned in an earlier thread about the illusive plate #77 and I have a plate #78. Are they really common? Also the the other one is a plate #200. I hope I'm doing this correctly; the plate number are those numbers in the scroll-work up the sides of the border right? I can re-post the hi-res images (if so desired) but I already posted them twice already. I can post the links here ~(below). Thank you for any enlightenment in advance. -Jay

the pics are located at bottom of the "penny reds?" thread.

Also on this post as well- "Some covers from this month/I got the penny reds!"

I posted in that thread a link to a document that tells you how many sheets and stamps were printed from those plates.

78 = approx. 178,000,000
200 = approx 65,000,000

So very common. Used value is $2-3.

you beat me to it Anthony

Thank you very much! Would you know what year(s)these were produced and/or possibly the scott numbers?
So basically no gold mine huh? Darn it. lol
I was just curios as I really love these stamps. I was contemplating buying a Penny Black to add a little flavor to my first page.

1864 Scott #33.
Being on a nice cover will be more valuable than the stamp on its own though as they are interesting items.

Which one is scott #33 the plate #78 I take it? The other is plate #200.

Thank you immensely! -Jay
