The silence from Alice was all the answer Archer needed.
He smirked, "Take care of yourself, don't overwork yourself to an early grave. Take breaks and hire people you trust to help out. Jint may be a blacksmith, but he's been spending his entire day drinking rather than working-I'm sure you can make better use of his time by making him work as a receptionist."
"But I don't have enough money..." She was already broke before Archer first came to the village and was sinking deeper into debt by trying to keep the Inn alive. Thanks to him she did manage to pay everything back, but it also didn't leave her with something sufficient enough to hire people.
"Here," Archer said as he threw a small leather bag clattering with metal sound inside. "This is for you, it should be enough to last a few months."
Curious about what the gift might be, Alice opened the bag.
"-!?"
And nearly dropped it to the ground in shock after discovering the contents of the bag.
"G-G-G-G-G-" She stuttered continuously in shock, until a coin hit her head and fell inside the bag.
"-Gold coins, yes, don't start screaming to the world. We don't want you to be mugged, do we?" Archer tried calming her down. Just like he'd expected, the main form of currency around her was metal coins made from bronze, silver, and gold-with some exception of natural forming metal imbued with certain amounts of magic known as orichalcum. Of course, this was what the books described at least. But those were extremely rare, being only used by the richest of nobles.
The value generally went like this. A hundred copper would equal a single silver, while a hundred silver coins would equal a single gold coin. Orichalcum on the other hand didn't have a fixed price point, it depended on how much the holder wanted to sell for and how much magical energy was actually stored inside it. Archer had theorised that these were just naturally occurring alloy veins formed near a Ley lines nexus. It would explain how they held any amount of magical energy in the first place. 
Anyways, a single loaf of bread would cost two copper coins or one, if it was becoming stale. A night's stay in the Emerald Inn cost about ten copper coins. 
So what Archer had given to Alice was a bag of a dozen gold coins which was enough for her to get by for more than a decade, if she stayed in the village at least. The cost of living in the capital would be much higher.
How did he get them?
Because they were fake, mere creations of Projection. He had retrieved a single coin from Maia without her knowing and duplicated it with his magecraft. On earth, normal projection used to create such items by regular mages wouldn't be everlasting, as it is recognized by the world as unatural, one that doesn't belong in the natural world and they would slowly fade away with time.
But his projection was unique in itself, again, in the world he used to live in, they would be everlasting as he tricked the world into thinking them as natural materials.
But this world was weird and Archer wasn't completely sure if they would last here forever, as that would imply that he just performed a feat of pure magic. On Earth, they counted as permanently stable items, but still not the real deal. He couldn't create real gold out of nothing, this was nothing but a magical construct. But since Alaya and Gaia didn't have that much of an influence in this world and that the rules were very different here; he was sure that they would last long enough.
But still...
"I would advise you to exchange the gold for silver as soon as possible. Ask Jint to help you out, don't do it on your own as people might try to steal it from you." There was a chance that these constructs would cease to exist at some point soon, maybe a year or two, and didn't want that to happen while Alice had them. After a certain time in circulation, no one would be able to trace them back to her, just in case they disappeared.
