Post-apocalyptic survivors and shredded paper as currency [closed]

There was this series which I saw during the 90s in which there are 4 to 8 survivors after a nuclear war. the survivors consisted of elderly as well as young people.

This is all I remember about the series (since I was only a child) but yes in 1 episode they decide to have a currency and they use some shredded paper as currency which starts conflicts and rivalries to the extent that by the end of the episode they decide not to introduce money in their new society and dump all the currency into a well!
