Please help me value these 19th century Revolutionary War engravings.

Hello,

I am trying to find a value for these two Revolutionary War engravings.
The first one is of British General Charles Cornwallis (Revolutionary war).
The second is of Horatio Gates - A US General of the Revolutionary war.

*Both of these images were taken from the New York Public Library website but mine are identical.


Cornwallis
Date: 1826
Stone, William L. (William Leete) (1792-1844), Author
Colden, Cadwallader D. (Cadwallader David) (1769-1834), Author
Ritchie, Alexander Hay (1822-1895), Engraver
Hoppner, John (1758-1810), Artist
Cornwallis, Charles Cornwallis, Marquis, 1738-1805


Gates
Date: Unknown
Trumbull, John (1756-1843), Artist
Hall, Henry Bryan (1808-1884), Engraver
Pate, William, Printer of plates
Gates, Horatio, 1728-1806

 

@Shawnshank, please go in to your post, click on the very TOP image that says "INSERT EVERY IMAGE" as a FULL IMAGE"....that way everyone gets to see them as full size....much easier for ALL!!! Thank you!

 

There's identical, and then there's seemingly identical, with possibly a big price difference between the two. You really should post images of yours.

 

small value

 

$35 (asking price) https://www.amazon.com/Charles-Cornwallis-engraved-historical-portrait/dp/B01DOHNTJ4
$18 on a coffee mug (plus other formats) https://grangerartondemand.com/featured/charles-cornwallis-granger.html

 

They both look like steel plate engravings from books. As blooey said, small value. I think that Amazon price is very ambitious; half that would seem expensive to me.
