Anything someone values can be made into and used as money. That ought to be Rule of Acquisition no. 1, but it ain't. The point being: if you want to make currency out of concrete or cement, it is indeed technically possible. CaM's answer is thus half wrong, because of Renan's answer. I'm assuming you want something something a little more portable than ...

If the spells only protect living creatures, and you need a portable form of currency, you are left with only one rational choice... I give you... ChinchillaCoin

This couldn't work at all. The reason why money needs to be "positive" is that the one with the incentive to have it is the one who has control over having it. If money is negative, you can just throw it away or simply never show anyone. The government 'requiring' you to keep it with you isn't gonna help because that's A) impossible to enforce and B) ...

All that gold makes gold virtually worthless so people would put it to practical use like construction. The Pantheon is held together with iron bars coated in lead to slow down corrosion. You could get better protection coating iron in gold. You can coat roofs in gold leaf for excellent waterproofing. The ancient Romans used lead pipes for water. Gold ...

Just use gold. Really. Yes, when you are walking on the sun, you need to keep it your magical purse tightly closed to keep the high pressure vapor from escaping. When you get back, it happily cools back down to a solid. Alternately, just keep payment within the magical boundaries. Carry your gems in your mouth. If you are selling the Bazaar on the ...

Melt down small amounts and use it to manufacture gold plated "ultra fidelity lossless" audio/video/network/iphone charger cables that you sell at \$100 -$500 a piece to pretentious fools. This actually gets you more than the market price for your gold! You may not have 45 million dollars at once, but you'll have a steady income for many years, and as a ...

It makes no sense, as the attackers will obtain all the gold of the besieged anyway, as soon as the defense has fallen. Selling food to the defenders is the worst possible action, as it increases the losses of the attackers who need to resupply, keep their troops healthy and motivated without being able to do much. Time is essential in a Siege. The longer it ...

You have a fundamental problem Bullets are incredibly common While they have intrinsic value, that value is going to be very low. It's like having a currency with only pennies. It could be fine and accepted, but it'd really hard to pay for anything high value due to the shear tonnage of bullets you need to haul. Mad Max implies shortage of food and ...

No Money, as we understand it, is essentially worthless, and it should be worthless. It serves as a medium for exchange, where a given amount of money is agreed to have a certain value, but the tokens exchanged are more or less valueless. There are good reasons for this. Bullets-as-currency would be a form of commodity money, a relatively primitive form of ...

Laws are local with that sort of money If you want to clear the whole lot out at once, you could to sell to a national government. The advantage of this option is that it's legal. If it's not strictly legal, they'll make it legal. Sell to an eccentric millionaire, the amount of gold you're moving, while heavy and a lot of money to normal people, isn't a ...

With some planing (buying 20yo money), you can go back to ~1929. Without any, you can only go back to ~1996. There's a pretty good chance of getting away with it, going as least as far back as 1929, assuming all your bills are from before 1996 (currency redesign), or even better, before 1990 (security thread and microprinting). If your (large) bills are ...

US Dollars, Euros, or any internationally strong currency used by humans in your world. Let's face it - most of our "currency" is already in bank accounts; not as any physical form but as electronic entries machines "understand" as well as, or better than, we do. What does a droid need? Maintenance? Spare parts? Power source? All of these can be easily ...

1) Business and commerce would be nearly impossible for three reasons: It's incredibly cumbersome, you can't make change, and you can't save. If the going rate is three loaves of bread for one jar of fire, but I only want one loaf of bread, the baker and I are stuck - we can't reach a fair agreement because a jar of fire cannot be easily divided. If I ...

Why the black market? You can just sell the gold and be done with it. Disclaimer: The legality of the following will definitely depend on the country you're in. The laws I'm considering are those of the Czech Republic. Where to sell Where I'm from, goldsmiths routinely buy gold off of people. When I was having my wedding ring made, I was given the ...

I don't see why not Disclaimer: This answer heavily depends on the definition of same economy. This answer also does not claim that a fix 1-to-1 exchange can be maintained. You already mention that the classic coins derive their value from the actual value (usefulness) of the metal they're made of (similar to e.g. the likes of hacksilver) - this is great, ...

The primary reason why gold is so valuable is because of scarcity. Once you eliminate scarcity there are many uses that gold can be put to. Chemically it is highly nonreactive making it a good fit for containing reactive materials and foodstuffs, and anywhere that you want a durable cladding that doesn't require much strength. It conducts heat well making ...

There is no reason that a currency couldn't span across multiple planets or even star systems. The key thing that makes currency work is trust, people have to be willing to trust that what you just gave them is genuine, and that they can then trade it on in exchange for further goods and services. So long as that problem is solved then even a galactic ...

I remember reading a sci-fi story many, many decades ago about a similar theme. I completely forget the title, or the author, it was so long ago, but I remember the theme, since it was so unique. It absolutely challenged all current economic theories at the time. It was written when resources were still considered infinite, and automation and computer ...

Let's start with a bit of a Frame Challenge: you really don't want perfect digital currency It's important for you to understand that you can always ascribe more magic to digital currency. You can declare it to be secure, less costly to use/process, better synchronized, etc., etc., etc. If you're going to do that, then why ask the question? Hard ...

Could it be used as a currency? Possibly. It is reasonably valuable and durable. There are some issues: Inflation Depending on how slow they reproduce, and how long they live, you could just get a bunch of "money" and leave it alone in the back closet for a while and it would breed new money. You don't even have to feed it. This means, concentrated ...

Possible, yes. But not useful. You could make a cement coin. It could be pressed into a shape like a coin with embossed details, etc. But it would be far too brittle to survive common coin usage. An unsupported piece of concrete roughly the thickness of a typical coin will shatter quite easily. So could fired clay or even carved stone at that thickness. ...

An example of a Gold-Silver-Copper coinage system The standard D&D gold/silver/copper system with its multiples of 10 comes from the Roman currency system of ~200BC-200AD. There were other Roman coins, but for the entirety of that time period, corresponding with the 'Classical' Roman 'golden age', the aureus, denarius, and as were issued in gold, silver,...

Use an animal as your purse. As already noted, since no form of matter can stand the temperatures required, the only way is to store the currency inside living things. There are many animals that can do this. For example, you can bring along a number of chipmunks, which will keep your money inside their cheek pouches. This has the benefit of maintaining ...

Money is chosen because money is convenient. Current prevailing opinions suggest a four major factors that affect the choice of a money: Durability: The currency should avoid devaluing over time Divisibility: It should be possible to use the currency for arbitrarily small transactions. Transportability: It should be easy to transport a great deal of wealth ...

In tribal warfare trading with the enemy is normal, even in the modern age in conflicts like the ongoing Syrian war. The factions were trading fuel and weapons, even though those same weapons would likely be turned against them. So the concept itself is not entirely irrational. It's very much a matter of the sort of war you're having. However, half the ...

The bills would be gone or decomposed - if they were simply left in the streets. As soon as the cities are abandoned animals and nature will reclaim the area. There are plenty of post-apocalyptic movies and video-games that will give you a great idea of how an urban area might look after a decade or more of complete abandonment. Consider what would have ...

The weird thing is that prices can be arbitrary, or wages can be arbitrary, but they must be highly correlated. Say the minimum wage is \$8/hour, for argument's sake. If I make it \$800/hour, commerce does not change if I also multiply all prices by 100x, so the minimum wage buys exactly the same thing. The people really damaged by that are the people ...

Not only is it possible, it has actually happened at various times and places throughout history and on small scales continues to happen today. Probably the best studied example of the phenomenon is the era of free banking in Scotland, 1716-1845 [1]. During this time three major banks and a number of smaller banks in Scotland all issued currency. The ...

Suppose as tax, the citizens pay their government with their time and labor. It is a reasonable idea - working on the government farm, serving in the military, washing dishes, etc. On my necklace I have tokens - coins if you will - that depict what I owe the government. The government has given me these coins as tax. If the government needs dishwashers I ...

If there is no exchange of goods or services then there is no value for each currency in the other worlds. Currency is purely defined by what it can be used to purchase. There for the question is a matter of what is imported or transfer between the two worlds. It's likely that some sort of exchange does regularly occur. If people are traveling between ...
