Two real ones from somewhere near that time.
The upper was from a leather ammunition carrier/pouch that Paul Klatt turned up and dated as ca. 1839.
The lower is pictured in Vol. 1 of Hoyem and has an advertisement noting 1825 vintage wine arriving into the port of NY printed on the inside. I’ve unwrapped it & it contains a poorly cast round lead ball & very course & uneven black powder.
My 2¢ is that anything that clean & said to be that old has problems. Paper in those days was 100% rag & none of this modern acid paper was used, before I bought it I ask to feel it. It’s too clean, and the string looks too nice & new. Also other was to check it if it was printed by type the paper would be impressed by the type with the ink into the paper & if from a Xerox machine the ink sits atop the paper. Also UV light could be used to check the paper for age.
