Нет, поздно . Швейцарцы плотно за тему уцепились. Уже не втиснуться.

Заметьте, как интересно сделан обзор в Nature Material. Про исследования в Эрмитаже не слова. Еще повеселило имя «русского» исполнителя тиары :

Material witness: Old gold

Introduction
In 1896 the Louvre museum declared that it had bought an ancient Greek gold tiara for 200,000 French francs — roughly  1.3 million today, but considered a bargain in view of the object's antiquity. It had allegedly been given to the Scythian king Saïtapharnes around the end of the third century BC as part of a bribe to leave the Greek colony of Olbia unmolested.
But almost immediately doubts surfaced, as experts questioned both the tiara's design and its apparent lack of ageing. The Louvre defended the item's authenticity, but then one day a Russian goldsmith named Israel Rouchomovsky came knocking at the door with an incredible claim. "I made the tiara", he said. He explained that two dealers had commissioned him to make a gift in the antique style for an archaeologist friend. Now news had reached Rouchomovsky of their true intent. When the goldsmith demonstrated that he could reproduce part of the tiara, the Louvre officials had no choice but to believe him. They quietly consigned the gold object to their vaults.
Were it not beyond the capabilities of fin de siècle science, a new technique for spotting forgeries of ancient gold objects would have saved the Louvre its embarrassment. Otto Eugster and his co-workers at the University of Bern in Switzerland say that radioisotope dating can be used to estimate the last time that gold was melted down (O. Eugster et al. Archaeometry doi:10.1111/j.1475-4754.2008.00426.x; 2008).
Forgeries of gold artefacts are probably the most difficult to detect of all fakes. Aside from stylistic grounds, the more objective criterion of patination is unreliable because gold's noble character leaves signs of surface decay tenuous and easily removed by cleaning. And gold has no intrinsic isotopic signatures of age, because it has only one stable isotope.
Eugster and his co-workers have for over a decade been studying the signatures of radioactive trace elements such as uranium and thorium that get incorporated into gold in the Earth's crust. Alpha decay of these elements leads to the accumulation of helium-4 in the metal. So measurements of U, Th and 4He in gold can reveal when it was last solidified, as radiogenic helium is expelled on melting.
The researchers proposed in 1996 that this approach could be used to date ancient gold artefacts, but only now do they have the instrumentation needed to put the idea into practice. It demands an ability to detect extremely small amounts of 4He, both because it will have accumulated for only a relatively short time compared with geological samples, and because such analyses, being destructive, must be based on very small amounts of material.
The Bern group has now used their dating method on a variety of historical gold items, ranging from gold bowls of the first or second centuries BC from Central Asia to a French gold coin minted in 1857. Although at present the method doesn't constrain the dates very tightly, the researchers found that all the ancient objects were made more than 350 years ago, whereas the French coin is of more recent provenance.

Чото подзадолбали эти спецы с форАПа со своими подбитыми глазами.

Короче, предлагаю любой глаз - хошь подбитый, хошь нет - за смешные 300 евро.

Образец продукции внизу - глаз устраивает?

Не за что. Передай там своему оппоненту, что монетка чеканеная.
Из той же конторы, что в частности и акрагасовские тетры лепит, штемпеля которых я в свое время на FAC светил.
