    Copper has a density of 8.92 and bronze 8.89, so don't expect to tell them apart via Specific Gravity.
    I can tell uncleaned copper from uncleaned bronze by sight,
    usually.....

    Hi, thanks for the response. These are in the form of minted coins. Is there going to be no way of telling by sight then? I can try and take pics if its still doable.
