Is this Colombia 5 Pesos Gold Coin Real?
Hello. Just to wanted to make sure this Colombia Cinco Pesos from 1920 looks real? Took some pictures in different lightings. I weighed it at 7.9 grams, and it's diameter at 22mm. It has dings/scratches, and probably has been cleaned.
FWIW: I put it in a glass of water and it immediately sank to the bottom (since real gold is very dense, it should do that). I know that's not a 100% accurate test; hence the confirmation here on the forum where there are more senior and experienced members.
BTW: Assuming everything looks good — would the "A" mint mark stand for Antioquia? I wonder if this was minted in Medellin.
Thank in advance.
