I have twelve of these, all different states. The edge says "24kt gold" followed by four symbols. I cannot make out all of them but there is a 76 and a P, both inside a square. The local gold buying place tested one and they it passed for 14k gold, not 24k. He couldn't find anything online about them so he didn't want to get involved. Anyone know what these are and why they're stamped 24k but testing as 14k? I believe his acid test because he rubbed the test stone with his own wedding band also and it yielded the same result as the coin. I'd love to know more about these because they are pretty nice.
