Got these on the internet and have some doubts after researching. They weigh between 0.5-0.7 g. Measure between 9/16-5/8? Non magnetic. If they’re real. What are they worth?
Those are Hungarian Denars. They typically weigh around that particular weight. Most examples tend to sell for $10 to $20.
@tibor I believe that these may be your forte if I'm not mistaken. From what I've been reading on Hungarian hammered coins, they should be approximately 0.58g and be about 15mm in diameter.
