National gold bank notes (NGBN), issued by nine national gold banks in California in the 1870s and 1880s, were national bank notes redeemable in gold. Printed on a yellow-tinted paper, six NGBN denominations circulated: $5, $10, $20, $50, $100, and $500. A $1,000 NGBN was designed and printed, but never issued. During the issuing period of national gold banks (1871–83), the U.S. Treasury issued 200,558 notes totaling $3,465,240. Today, national gold bank notes are very rare in the higher denominations (and unknown on some issuing banks) with condition generally falling in the good to fine range. Approximately 630 NGBNs are known to exist, and roughly 20 grade above "very fine".
