Purchasing Power (General Idea):
Copper Coin (Speck): Enough for a small, simple meal (like a bowl of stew or a piece of bread) from a street vendor, a single piece of cheap fruit, or a basic measure of local ale. Common laborers might earn a few copper coins a day.
Silver Coin (Shiner): Can buy a decent meal at an inn, a common tool, a sturdy pair of shoes, or pay for a night's stay in a modest room. A skilled craftsman or a soldier might earn a few silver coins a day.
Gold Coin (Solar): A single gold coin represents significant wealth for the common folk. It could buy a fine suit of clothes, a week's stay at a good inn, a small plot of rural land, or a rare ingredient. Master artisans, prosperous merchants, or lower-tier nobles would deal regularly in gold.
