Hello and welcome.
Unfortunately, your "coin" is not actually a coin. It's from Indonesia and is one of a class of objects known as either "pilgrim medals", "hajj tokens" or more generically, "magic coins".
This example on zeno.ru appears to be much the same design, though there may be a different design on the other side.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
