Thank you for your post. The document issued in 1880 is most likely the nineteenth century version of a passport - which would provide documentation and give your ancestor access to American Consulates and Embassies as he or she traveled.
We hope this information is helpful. Best of luck with your research!
Thank you SO much for your response - this makes total sense. So fascinating to learn about this document and how it relates to my ancestor.
