The frozen date of AH 978, translating into 1570 in the Gregorian calendar, is a good give away for an old dokdo from the Indian princely state of Nawanagar (today known as Jamnagar). Typically around 7-8 grams, these chunky coins were struck from the late 1500s through to the early or mid 1800s, all with the same frozen date referring to the accession year of Muzaffar Shah III of the Gujarat Sultanate. His coins circulated widely, and the design was copied again and again until the '9' became a blundered vertical line. The 'V' and ' ' shapes for '7 and '8' are still legible. The same frozen date can be seen on the coinage of other princely states of northern India. Values for these coins follow below:
worn, crude specimen: $6 US dollars approximate catalog value
average circulated, decently executed: $10
well preserved, attractive calligraphy: $15
The later the coin, the more degenerated the design. The weight average also seems to be lower among these later, cruder specimens. Collectors prefer earlier, legible coins with an attractive calligraphy over later, blundered coins with inscriptions squeezed unto the flan.
