Alexander returned from his visit to the mint with a few pre-made dies and even a ropal gifted to him as a souvenir.
And as he held up the coin which had a hole in the middle, and noticed the various markings along its borders, he felt he had learned many new things today.
First of all, it finally became clear to him why the ropal, and for that instance, many other ancient coins in his previous life too, had a hole in the middle.
This was done so that the coin's size was large and convenient enough to hold in one's hold without having to add too many precious metals and hence make the coin's value too big for everyday use.
Then, aside from the usual engraving on the coin, came the small markings along one side of the side.
These were actually codes, detailing the coin's origin and production details, including the mintmark, which identified the mint where the coin was produced, and the control marks, which indicated the responsible authorities overseeing the minting process.
