Ow3qa I think it would be a good idea to post a photo of the reverse aswell and give the size and weight Saludos Paul |

The coin appears to be very old!
Losing the real weight and size.
I saw on another forum a topic with an identical coin, the story of theat coin made me ask question!

This should be in silver. This looks like a base metal cast, especially with the softness of the detail and the pitting.

Your coin is not identical. It is from different dies for a start. The coin you point to is also a cast fake in base metal (bronze/alloy).

 It seems to be a fake, but the chemical test indicates 8 k gold, what makes me think that may be a electrum decadrachm!   Edited by Ow3qa

Your edge photo adds to the conclusion that regardless what the metal tests return it is a cast fake. There is evidence of a casting seam which has undergone mechanical filing to make it in areas. You can clearly see these file marks on the edge. The divot you see is the remnant of the casting sprue.
The bubbling and soft characteristics are also evidence of casting.
You could send the coin to an independent expert for confirmation either but I think that this would be wasting your time and expense.
I cannot say more than this and it doesn't look like you can be convinced either way so I will move on and wish you well.

Thank you for showing pictures, particularly of the edge.
I have never heard of an electrum decadrachm in this series. I do not recall seeing anything in the numismatic literature in this series as regards gold being used in the alloy of Syracusan decadrachms.
8 ct gold used in the alloy should go a long way in helping to protect against corrosion, and so I find it difficult to understand why one should see corrosion to the extent shown in these pictures.
The edge pictures show evidence of tooling to remove a circumferential casting fin. I can understand your reason for letting us comment in this area. The file marks show no evidence of corrosion at all.
I agree that pitting indicates bubbles characteristic of low pressure casting.

Thank you all for your responses! I had doubts but I was not sure about the coin. Coin edge is what got me thinking from the beginning ! Thank you and I hope this topic will help in future to detect Fake Decadrachm  ! Edited by Ow3qa

Certainly keep this piece. If it is solid 8ct gold and not plated, it should have a little over $300 in gold value.
If it is gold plated, it has only educational value in learning how to identify fake coins. That is OK. I have quite an extensive collection of fake ancient coins, the existence of which is to educate myself on them, for my own protection.
If it had been very thin plated many decades ago, the purity of the plating will decline over that period.
I had a .925 silver coin plated 40 years ago and it appears to be a lot paler gold color than when I originally had it plated.
I was told the the reason for this, is that at the interface boundary of the substrate silver and the gold plating, a cross migration of gold and silver atoms has taken place, and so with very thin plating, some of the silver atoms have made the gold plating look paler than when it was originally plated.
The same sort of natural process may be happening with this piece also.

Thank you all for your time to light me with this false coin. I am deeply grateful to all! I foundon on http://goccf.com/t/281372 , a discussion about a similar coin, is a fake identical to the one I had! It appears that these fake coins can be found in my Country. Edited by Ow3qa
