Using the Charlton's Cataloguing system your note is a DC-1c (a "plain" series letter note because there is no series letter A or B below the year 1870).
Actually in my opinion your note is in pretty good condition since a minimal amount of the design has worn off - a little bit is worn off on the back of the note in the vertical fold in the centre.
From the scan I can't tell if there are any pinholes but you appear to have a note grading between Fine and Very Fine. Using last year's Charlton, a Fine is worth $50 (book value) and a Very Fine is $100, so yours is probably in the $70-$80 range.
