This coin here was sold to me as being 1 Dokdo, 1850, Nawanagar. Visually, it appears to be N#48330, but the main concern I have is the weight. Here on Numista, N#48330 is listed as being around 6.4g, but my coin is almost double that at 12.5g. I was hoping to find help confirming it's validity, finding it's Numista page, or gathering information to create it a page if it doesn't have one currently. Below is any relevant info that might help:
-Smells very strongly like copper
-Is about 20mm at it's longest point
-Is about 4mm thick
-Weighs 12.5g
-Has an alignment of about 10 o'clock
-I've bought many coins from this seller previously, so I don't believe it is a fake (Or at the very least I don't believe he knows it's a fake if it is)
Any help is extremely appreciated!!
