Greek Coin Cleopatra Thea Question

[amanapro]

Someone showed the Greek silver coin of Cleopatra Thea, 126-125 Tetradrachm. It is diademed, draped and veiled bust of Cleopatra Thea right. Rev. double-cornucopiae tied with fillet.
My question is the coin weight is 41.10 g, but when I search the net i did not find that kind of weight for this coin. it was only somewhere between 15 to 16 g. So can a weight of such coin exist?

At that weight it would have to be a Deacadrachm, and I don't know of that denomination with a portrait of Cleopatra, but I'm certainly no expert on these huge silvers.

Here is one of Arsinoe II under Ptolemy II that could be similar to what you describe? with a weight of 35.86gm. At 41.1 your coin seems even heavy for this type as they seem pretty consistant at around 35.5gm
