celtic coin?

[bunne]

Hi,

This is my very first post on this forum so if thanks for the effort you guys take to help me for determine this coin.

I found this half coin in the neighbourhood where celtic people have been living (eastern part of belgium), I found a roman coin too in this area so could be roman also.

Material = silver

Diameter = 15mm

Thickness inner side = very thin (like a sharp knife  (dont bother reading the text, its dutch ;-)
Thickness outer side = almost 1.5mm thick

The two red half circles i drawed are kinda pits, so i think its maybe a cross 

I am not sure, but i think i can see an "O, G or C" and after that i think an "i"

the weight of the half(!) coin is approximately 2 grams

the back side is not very helpfull, still a black spot i need to clean (I think there is a little sleef at that place)

thanks very much for the efforts

I don't think you can tell anything from the picture, except that it's probably half an ancient coin.
I can't even read some of the text, let alone see the things that I'm supposed to see.
Can you post big, clear pictures of both sides, without the painted text and arrows?
