    They are both the same type coin.

    I just want to ask what the reason for the two different color/patina is? Is it because one of them has lesser carat? Or is this because one has been cleansed/soaked and thus it shines more?

    If you hold them in hand they do have different color/patina. If you look at image 3 and 4 you will see that the left one is more "orange"-coloured than the right one. But perhaps I should have take a better foto.

    Top coin, reverse, figure on the left looks like Kermit the Frog. Just wanted to point that out :)
