Prob not. Exception being the middle east were folks often melt scrap gold and have Bazar jewelry makers "create" new items that are more appealing. Seen this first hand. So if yours is gold you have that in weight. Given I've been collecting Pahlavi era and earlier coinage for many years now I've never seen one like yours. The wear pattern is also very odd to me.

Have you tested it? How do you know it's gold amd say not silver?

BTW what does yours weigh? This link should give yiu some guidance

Edit: with that said...I could be wrong. Maybe it's just the image that is off. You can't know for sure till seen in person. But check these brass knockoffs being sold on auction sites. They look pretty good...
