A quick internet search valued gold coins from 40 to 1000+ Euros, depending on the coin. So maybe not too bad for a day's work, maybe less than minimum wage, depending.
Though if you multiply it by 100, that goes to way too high for a guy like Parsons to earn. The economy of that thing's completely out of whack.
On another note, I wonder if the tutorial thing means that, looks aside, the MC was never in any danger?
