Recently I have been reading Adam Smith's A Wealth of Nations. Today, I remembered this game existed. These two happenings have resulted in a coincidence where I looked up if coins exist in this game, in an effort to learn about the economy of the virtual society found within. I read this wiki page: https://havenandhearth.fandom.com/wiki/Coin and immediately realized the problem with coins in this game, by relating it to the philosophies and observations laid out by Smith in his work.
Let me first summarize why coins have failed to be useful in this game, according to the wiki page: Simply, they are too much trouble to make, and do not serve a useful purpose. They have no value in use, and no value in exchange. The reason they have no value in use is self-explanatory, but to emphasize, it is because they cannot physically be used to accomplish any task and are not inherently wanted by a person. The reason they have no value in exchange is partially derived from their lack of value in use, but also because the labor cost to make them outweighs the power of purchase they command over the economy. The only use at the present moment seems to not be useful in such a sparse world as this old one, which is that use from being of the role of short change.
In real life, so-called ancient times to be specific, similar to the current game world, according to the wiki (as I am not a player myself at the moment), raw bullion, or bars of metal were exchanged in preference to coins. The reason that this practice eventually died out is due to two main factors that are not present in the haven and hearth mechanics: the requirements of weighting and assaying. To break it down simply, the following analysis. The main reason coins were initially created in real life, is because people did not know if the bars of metal they were bartering for were actually made of the metal they expect them to be composed of. Fraud, scams, and tricks were all present and common. A government stamp ensured a seller that the purchaser was using real precious metal, be is silver or copper or other, and not some trickster alloy. This is not present in the haven and hearth world, and by easily mousing over an item I presume it is entirely possible to assay and ascertain the material of which a bar is composed within seconds. Take that as you might for an idea, whether it be one for stamping or for alloying or for both.
The second reason coins were made was actually addressed later in history, which is that of weighting. Accurate instruments are required in order to weight the mass of metal being bargained with. Eventually, the weight or mass of a coin was standardized by feudal governments. In haven and hearth, this is already accomplished by bars. A person can clearly see how much metal is present in a trade, and there is no weighting question considered.
So, the combination of a lack of weighting requirement (as the amount of metal is clearly defined in the game's mechanics, and is not questioned), and the lack of assaying requirement (there is no possibility for suspicious alloys, and no requirement for officiated stamps), means that coins are virtually useless in the game's economy, and the economy is perpetually stuck in the same age of improvement as the ancient roman kingdom (not even the empire, mind you).
I will concede, that while coins do not fulfill this role in real life, that coins fulfill a role in the game, that which I mentioned earlier, which is short change. Utilizing coins, a buyer does not have to buy in bulk a set of commodities, and can purchase in more precise quantities due to a dividend of currency provided by the smaller sizes of metal provided by coins. However, if any alterations are made to the game based on the weighting issue above, this role that coins currently fill will be useless, because just as in real life, I would imagine metal could be divided into smaller amounts without making it into official coins.
I suppose I would propose the following changes, though forgive me if my ignorance of the game itself shows in these suggestions, for the last time I played this game was long ago and for a short time then. The changes are:
1. Make it possible to alloy precious metals with coarser metals, or just metals with any of each other in general, and do not display the specifics of the alloy upon simply mousing over, some assaying process could and should be implemented.
2. Do not count quantities of metals in integers, and/or do not display the quantity upon a simple mousing over. A floating value should be used to mechanically express quantity of metal (forgive me if it already is this way), and the amount should not be precisely discernible without some form of weight measuring tools. Of course, a glance could give some idea (qualitative measurements, such as, but not limited to: a color and texture description, phrases such as "a lot", "a little", "a handful", etc.), but a measuring skill or tool would be needed for accurate figures.
3. Make the coin creating machine customizable, so that each coin machine can print a different design (mechanically, this could be limited to a message upon observation or some other abstraction), that way each nation can print its "own currency". This would also progress the game towards a more national focus and less tribal focus as each government would need to define and assay the metals used in their coins, as well as provide their own stamp, and for some common folk, this stamp may be the only way they fully trust a buyer, advancing the notions of both government and currency.
That's all my thoughts for now, I hope someone thinks this was at least interesting to read, but I especially hope the game developers take notice and make these or similarly intended changes.
