That was the spot for Copper Coins, because all Goods brought to the market were supposed to be for other Goods from the market.
Any plus in Local Coins was given to the Church for the poor or spend in the Market Kitchen.
That was the early Mid-Ages on Farmer Markets.
In many of the poor areas of this world all basic Goods are again produced and sold locally, especially in rural areas.
In the currently dominating Monetary System many will have to provide their basic Goods by an Egg for an Chicken deal by having both buyer and seller cut off from money or having trouble matching the needed amount on the market wasting incredible amounts of productive or recreational time.
Stock Exchanges were set up way before Company Shares were traded to be able to match buyers and sellers based on the same Good.
From avoiding Egg for a Chicken deals markets avoided 2 Eggs only for a Chicken No Deals putting all Eggs in one basket and all 2kg Chicken in one cage.
In many areas in especially the 3rd World local markets could trade without the need of using a national currency, if they would have a Computer create a mini Stock Exchange giving our Jetons, just like Monaco.
This way a seller offers his Eggs based on demand, if he likes how many Chicken are offered based on demand and offer, just locally instead of face based.
The side effect is the actual trick:
No Money, No Drugs, No Theft.
But happy new Egg and Chicken owners.
