I blew the reverse picture up, and from what I can tell it looks like you have the Stemless Wreath variety, which would make it 1804. I had the exact situation with my 1/2 Cent, and checked all coin books until my eyes bugged out. I finally realized that mine did not have the stems coming off the lower end of the wreath, just as yours seems to be. The only year they minted this variety was 1804. Congrats on a great coin.
