Julius Caesar Denarius Silver Coin, the weight of the coin is 3.87 grams.
The color of the coins is proper silver, on the photos they look like gold, but this is because of the flash of the camera.
Found this in abandoned storage room at Rotherham, the previous owner of the room was a doctor, it's a collection of around 80 coins. Spoke with friend of mine who is a collector and says that the coins are genuine. Anyway, you are free to make your own research and if you are not happy, you can return the coin back to me in two weeks after delivery and I'll happily refund your money.
Happy biding and God bless.
