Maybe this overweight fact will be worrying. I have been checking my other Wire Larins. The two from Bijapur are about 4.7g, while the only confirmed Sefavid specimen I have is 4.90g. My Ceylon fish-hook specimens are even lower in weight at between 4.5g and 4.8g.
It is difficult to be sure what other Maldivian Digu (Long) Larins have been issued, as I have had to rely on relatively poor quality pictures of poorly engraved or struck specimens. The only ones I can be fairly certain of are those of Sultan Muhammad 'Imad ad-Din I (1029-1058AH, 1620-1648AD) and his son Ibrahim I Iskandar (1058-1098AH, 1648-1687AD). However, none of those few coins I am aware of are of the same quality of engraving as my specimen, or have the same legend. There is an eye-witness account of such Larins being struck during the reign Sultan Ibrahim III (993-1027AH, 1585-1609AD), but so far I am not aware of any confirmed specimens surviving.
Like you, EWC, I am not active on Facebook, but if anyone does want to contact Stan Goron, or anybody else, for their opinion on my piece then I would be grateful.
