How much is un peso 1947 mo 14 gr 0.500 worth?

The coin is 14g's so divide that by 31.1 (31.1 g = 1 tr ounce)to decipher how many troy ounces that is....comes out to .4501 ounces but it is not pure .999 silver, it shows 0.500 silver so multiply .4501 by .5 and your answer is ASW of 0.225 troy ounces of silver which at todays spot price of around $28/tr ounce comes to $6.30 give or take dependin on the price of silver. I'm not counting numismatice value of which I think this coin comes in at around lower than its silver value
