I have two Circus Cards from 1882, Daisy Belmont and Major Littlefluger, both are midgets who traveled with the Sells Bros Circus across the USA giving out trading cards to promote their acts. I've checked the circus history sites and others, but no one knows much about the cards. My grandmother saved them, in very good condition. Are they worth grading? Can I grade them at SGC?

Thanks,
