Hello and welcome to the forum.
The design looks like a Spanish 8 Real coin of 1701. The problem is that the 8 real was minted in silver not gold. The weight is also off the 8 real should weigh 27.7 grams, even the gold 8 Escudos of the period should weigh 27.7 grams. Sorry to say but I think this is a modern reproduction of an 8 real made to look like a gold coin.
