Introducing a new local currency after an event

[grumpy old man]

hi without money?
i guess that you would have to trade what ever you have. If you need a cart from a carpenter then you have to give him what he is asking for.
If the price is too high then you walk away, this works for everthing i dont want money in a new world.
Only people that can not do anything, lazy people need money. If you have sick people in your family then you should carry them.
If you trade things as a currency then the value will always be there and you can trade with any one, if you use something like money it will only work in your area.
unless your the king with an army and tax collectors and a royal mint to make your money.
