Hello again,

Please provide diameter and weight in the future, so we can help you out better.

Your coin's been misattributed; it's actually from the reign of Gia Long (1802-20), and the seal script character on the reverse tells us it's a 6 Van coin: https://en.numista.com/catalogue/pieces57855.html
