Monetary Systems for Alternate Dimensions with low to medium tech/magic:
Roll a 3d10 to get a number from '3' to '30':
===============================================
3-There are sixteen different types of barter chits to use. If one has a cow, then you take four 'animal' chits, and try to trade them for chits that represent what you want. This chit system allows you to avoid having to carry a bushel of corn, or tote a cow through market. The chit represents that good. All goods in this fairly primitive society are divided into limited number of typed. Sumer had sixteen chit types.
4-Three chit types: Plantfood, animal, and clothing are used in this simpler barter system.
5-Time Hours are banked by someone agreeing to serve an hour in exchange for them being able to require the service of another who owes an hour to the bank. This is a more egalitarian system than money as everyone has only so much time, and thus the price paid to experts is much closer to the price paid to non-experts.
6-Pounds of Pepper are used in some medieval society as payment.
7-Salt is more common as it is neccessary for life.
8-Koku is a unit of rice production used in feudal Japan, and elsewhere in the Multiverse such as on the Planet Oleander in the Psyclone Station setting.
9-Copper, tin, lead shekels with barley as 'small change' has been done with the richer sort using silver shekels and rings.
10-Leather branded Triangles with some group symbol hard to make are one method.
11-Baked pottery 'wheels' with a rattle inside it are used by some cultures. If the wheel is damaged or the rattle is let out, then the wheel has no value.
12-Glass beads are a popular choice. Some hi-tech societies use holographic storage beads for a similar purpose. This can be to trade with less sophisticated peoples, or as the primary money since it can be made very hard to copy.
13-The Roman Denarii is worth one day's wages for the common laborer.
14-The Deben is an Egyptian money that weighs in at three ounces. For larger amounts of money, it can be found in short rods.
15-Silver shekels: A shekel is a nugget weighing close to 1/3rd of an ounce. Their use is very common. Gold and other shekels are used as well.
16-Silver coins (For example: Denarii, Lancaster Marks, Francs, Silver Pennies, Gleams, Silver Pieces, Silver Eagles, and JFK Half-dollars).
17-Paper Fiat Money. This money is given value by the statement of the government, and by its legally being legal tender. (For example: Pounds, Dollars, Rubles, Newbucks, and Yen.)
18-Gold Redeemable Dollars/Pounds/Yen/Bolivars. You can take your paper dollar (or other note) and take it to a bank, and ask for and receive the fixed amount that that dollar is worth by definition.
19-State Dollars. Individual States, Provinces, and Regions have their own monies.
20-Private banks are able to print their own dollars, and these dollars are backed by the wealth of the principal owner.
21-Company scrip has been used in many company towns.
22-Cowrie shells are clipped, and put on a string as a method of storing wealth. Sometimes these necklaces are a hundred long, and the money is stored by hangin it under the owner's arm.
23-Cigarrettes can be the basis of a monetary sytem.
24-Time Hours are a local currency where local businessmen are contracted to accept them. This is a method for an oppressed community which has its skill underutilized since the regular national currency has been sucked out of the community.
25-Clean drinking water.
26-Sealed drinking alcohol is one form of money to many.
27-Chocolate can be used in cold climates.
28-Ounces of various types of dye with royal purple being the most valued.
29-Ounces of Saffron and Yards of silk form the basis of this monetary system.
30- As on the Isles of Yap, giant stone circles and cut out, and made to serve as money. These circles are usually placed in front of a house. They might not be moved even when spent. Instead, ownership is verbally transferred.
