[Godebert]

"Roman coins are fairly common in Europe. They’re worth more as scrap, most likely."

907,184 grams in a ton. Half a ton of coins in this hoard. That is 453,592 grams. Approximate weight of each coin = 4 grams. That's about 113,398 Roman coins in this hoard.

Based on the example coin shown in one of the photos (Constantius Chlorus - father of Constantine the Great) and it's condition, the value of each coin on the collector's market would be roughly $50.

$50 x 113,398 coins is $5,669,900. That's a little better than scrap.

Price goes down when supply exceeds demand.
I’ve seen Roman coins for sale for much less than $50.
If all these coins are suddenly dumped on the market, on which there is already a good supply, I’d expect a very steep drop in price.................
