This rare series seldom is available for collectors, and we have only handled this 5 Yen denomination a handful of times. The note is part of the short lived 1877-78 series, with only the 1 and 5 Yen denominations issued. This 5 Yen piece is VF quality, but still retains very pleasing detail and is mentioned with only Internal Damage, and Paper Pulls.
