Volga, SD - Ch. 6099 - $5 1902 Blue Seal This is the only national bank ever located in Volga, South Dakota. This charter also happens to be the last bank in the country to open as a second charter bank. So if you are into firsts and lasts, then this might be an interesting addition to your collection. The note itself happens to be very rare without any special qualifiers. Just four large are known and this is the highest grade of that group.
