Myisa Kyzikos 2 Coins

I am not sure if its just the photographs or the colour of these seems wrong.

Electrum is a mix of silver and gold...these all have a deep golden colour. Maybe that is an effect of the lighting or the camera but they should be a light sivery yellow colour not like a deep 18ct colour.

The last photo also seems to show a colour diferential around the edges of the incuse... this could be refelction or a guilding coming off to reveal an underlaying metal.

It really isn't easy to prove one way or other but my gut tells me not to trust these coins despite not having any foolproof arguments.

I am curious what other members think.

And last pic. Edge's it's not different at all in flesh. End they much lighter yellow .. soon as I can I'll take new picture with out making any change.
