Could it be original? 3,2 g, macedon drachm
« on: March 21, 2023, 04:13:14 pm »
Dear Colleagues,

We stumbled a mystery coin with stragely rough surface, and we can not decide on our own what is it.
Please help us with your advices: crystallization? 3d print? casting? any other option? (the most common theories we collected...)

Thank You in advance,

I see a Sigma on obverse and no monogram below throne so it should be Price 1771

The edge looks manipulated, file mark.
The weight is too low.

We have to be very careful, there are 2 different kinds of crystallisation.

Some metals like silver can start to crystallize depending on temperature, environment and they alloy (how much silver is in the alloy), this will really take a very long time to happen.

And there is another crytallisation, related to the cooling down process, I think it will occour if the metal cooled down too fast.
This crytallisation can be found on gold and silver bars and blancks and on cast fakes. And I was told about casted "Blumengeld" with this surface.

Imho the crystallisation is here from fast cooling down.

Another crystallized cast fake, auther did not understand that the crystallisation was there already from casting and has not been prduced later.

And two Alexander cast fakes with such surface 13,4g (mother was authentic) und 14,4g (mother was a fake from modern dies).

Pictures larger than 2mb so I will add the Alexander cast fake 14,4g (mother was a fake from modern dies) here.
Same cast fake offered twice.

Dear Din X,

Thank you, you have thoroughly reasoned your standpoint, not much doubt left.
