This piece is solid 14kt gold & the moulds are from the original gold escudos from the Atocha. This is NOT an original gold coin, but instead I use the moulds from the original to get a museum quality replica. Please keep in mind the original gold escudos from the atocha start at around 20k & up. This is a great piece, solid 14kt gold, & has the same look. Atocha Solid Gold Coin 14Kt
