How to verify a coin is authen...

Got a gold coin online from a seller who seemed legit, but now I’m second-guessing it. It looks okay, but something feels off. What’s the safest way to verify authenticity without sending it off to a grading service right away? Any tricks to check at home first?

That gut feeling can be a real lifesaver. I always check weight and diameter first, but if you want a second opinion, try Coinstrail. They show exact specs for coins (metal content, size, weight), so you can compare yours right down to decimals. I once caught a fake because it was a few grams off. Plus, you can see photos from real auctioned coins for visual comparison. It’s quick peace of mind.

Just measured it — turns out it’s off by 0.6 grams. And the edge looks weird compared to the pics on Coinstrail. Might’ve dodged a bullet there. Thanks for the heads-up!
