Sierra,
Welcome to Treasure Net !!
If it were an escudo, it's diameter would be about 24 mm (compared to the dime at about 18 mm), it would weigh 6.77 grams and be composed of gold. Personally, I don't recognize the piece as an escudo nor do I recognize it as even a coin. Is is made of gold?
How did you come upon this 'coin'? Dug, purchased or gifted?
