FYI, typing in "1791" in numisma's basic search reveals 438 coins. Typing in "1791 copper" reveals just 141. Typing "1791" into the year for the advanced search reveals 354 coins. Measuring the diameter would've netted you just 21 coins if you typed "1791" into the advanced search for year and "29" for the mm. I don't mind helping out, but it took me longer to find it than it would've for you to simply measure the coin and search it.
