Hi,

I'm requesting help in identifying a mark found on a 1750 Brazilian gold coin. The mark appears to be the letters IG, with a crown above and a cross or fleur-de-lis below. It is punched atop a bold plug at the center of the coin and is double-punched. The coin was likely plugged and marked in New England sometime from the 1770s to the 1790s, based on the weight (215.44 grains) and the economic standards that were prevalent in the area. The mark is stylistically similar to Boston silversmiths John Coney and Joseph Goldthwait, though Coney was working much too early. Any help as to where I should look next will be greatly appreciated!!

-James

research "regulated gold coins" if you haven't already. only a limited number of silversmiths were known to regulate coins so that should narrow down the search considerably. if you own one of these you likely know this already since my understanding is they are fairly rare.

I would also add that it is really impossible to identity marks without a picture of the mark. If you can I suggest you add a picture.

Hi,

Thank you for your responses. I am quite familiar with regulated gold coinage, though this mark is rather puzzling. Please see the image below. Thanks.
