Look at the beginning of the video, there is all this dirt on the coin. In fact, it is not known what the coin is made of. If I had known it was gold, I would never have cleaned it so much.
The coin is a Roman sestertius and made of bronze. The letters SC on the reverse confirms this. If it was a Roman gold coin of around the same age (a solidus or an aureus) it would only need to have the dirt rinsed off as the gold would not tarnish or corrode even after almost 2,000 years in the soil.
LVERVSAVGARM PARTHMAXIRP VIIII SESTERTIUS BRONZE - Ancient Rome Lucius Versus Fake (tourist coin) (counterfeit) 161Ad to 169AD Lucius Verus was Roman co-emperor with Marcus Aurelius, from 161AD until his death in 169AD. Several different types of coins were made with his likeness, but this is not one of them. This coin is a large (35 mm) replica made to sell to tourists in the region of the old Roman Empire. Value is a few US dollars. These coins appear in various shapes and sizes, including silver and gold plated versions. The plating adds nothing to value.
SC stands for Senatus Consulto - senate was not allowed to mint gold coins under emperors, and in republican era was no gold coins in Rome as far as I know.
Thank you for your good information, it is a fake coin, but the material of the coin is gold, the value of this coin is only the amount of gold in it. The people who forged this coin were looking to make an ancient artifact. The coin is made of gold. When someone tests the coin and sees that it is gold, he believes in the ancientness and history of the coin.
