I present to you an unknown piece, after long research I am sure that it is about a piece of this type, originating in Syracuse.

However, I can only find silver coins, but this one is in bronze and I find absolutely none in this material. Can you confirm me?
PDM: 5,42g / 19,7mm / bronze
Thank you in advance :)
