I am pretty sure this is a fake, but make of silver instead of electrum. This is the closest “authentic” example I found. https://www.cngcoins.com/Coin.aspx?CoinID=329737 It appears to be a die match to this example in the Forvm fake coin reports.
Not sure which is your question!? Here is a nice authentic one https://www.acsearch.info/image.html?id=3091513
Other than Forum's fake database, I have no knowledge of this coin type. But if you've found a fake match, which it appears you have, I would say fake.
