Inherited Some Random Things. Could This Be A Real Golden Roman Coin?

Hello and welcome.

Nobody, not in Egypt, Rome or anywhere else, is going to take a genuine ancient Roman gold coin, and glue it to a piece of cardboard. So no, this is a "tourist replica", intended for sale to tourists but not really trying to fool a knowledgeable collector.

Note that if it were a genuine ancient gold coin, then it would still be shiny. Gold doesn't corrode, rust or discolour under normal circumstances. If the dinosaurs had made gold coins and we dug some of those up, they'd still be shiny too. This is of course why people like gold so much. However, your piece is not made of gold.

The Romans did make coins out of brass, which can look golden-coloured if it's polished up, but this is not one of those brass coins, either. The overall blurriness indicates this is a cast replica.

"Between 336 and 280 BC" is also way too early for a Roman coin. I can't quite tell which emperor is being imitated here, but probably an emperor from the 1st or 2nd century AD.

acetone did not take the gold color away... but thx guys
