Very interesting, thanks for sharing. I’d like to hear more of your stories.
Ahoj.
Colleagues, there was a lot of interest, so I will introduce you to our Czechoslovak socialist coins and now I will focus on their usefulness.
There are coins that are completely useless and yet there are coins without which life was not possible with Czechoslovakia for 60-70-80 years.
Here are the pennies described: https://cs.wikipedia.org/wiki/Hal%C3%A9%C5%99
Absolutely useless coins: 1 penny and three penny
no one carried it in their wallets at all - shops did not demand this amount and the goods were not even listed as such on the price tags
Example: 2.62Kčs
or: 4,38 Kčs so you never met this in Czechoslovakia.
Even the 5 penny was rarely required and few people carried it around-hardly at all. Here are:
1 hal.
do not underestimate the price of 480 CZK -21,09$
Even the capitalists did not want to live without it - but completely useless work:
Such an intermediate step for two years - Czecho-Slovak Federative Republic (Moravia and Silesia are forgotten again)
conclusion: coins useless unused lay in the bank
I don't remember this coin from my childhood or adolescence
conclusion: coins useless unused lay in the bank

they were sometimes in wallets, but few, and stores did not write this coin, did not require it on the price tags -nothing could be bought for it.
You wouldn't find a price tag in a grocery store 6,46Kčs ( designation of the socialist currency of the Kčs) either there was 6,10,6,20 or 6,25, 6,50
Often and daily used - always required and useful:
do not underestimate and immediately check in your collections just find the dots next to the year -298,74$
Daily used and useful:
The capitalists continued 
Special use:
There were few telephones in households in smaller towns and only a few in villages, so there were telephone booths everywhere - for calling. The price for the call was set at 25 halers - however, the machine did not exchange or accept other coins - only 25 halers. The need to carry was useful and used.
800Kč- 35,15 $ don't underestimate this species
koruna, 2 and 5 were standard paying circulating coins, and the three-crown was not used, so the Politburo of the Communists decided to withdraw it.
However, I have also experienced paper banknotes of the lowest value when I bought croissants on a change - they were used little and were eventually withdrawn from circulation:
3 kčs:

and 5 paper crowns:

And here is the expected one.
A story with socialism at the beginning of the 80s
The first Son was tiny - the wife was on maternity leave, I was studying at a military school ( where we were taught how to defend ourselves against the capitalists who wanted to own us and wanted to attack us and rob us and destroy us with their greed)
This defense strategy of the Warsaw Pact was based on the immediate reaction of the first-line units near the borders in the direction of Karlovy Vary - Plzeň - České Budějovice -After the initial stoppage of the attack, we were to immediately switch to an overwhelming counter-offensive, after immediate mobilization (6-12 hours), shooting practice and within a few days of the start of the defense, we were to stop at the gates of Paris.
( As a young engineer—an army type who built pontoon bridges, and I was to be a bridge company commander—I had my own maps for crossing all the rivers on the way to Paris- the tables contained the width of the river-ford-streams, its slope-depth- and the possible terrain of the banks, their strength-hardness) So that I was ready to build a pontoon bridge PMS https://acr.army.cz/technika-a-vyzbroj/ostatni/*kopie-1:-pontonova-mostova-souprava-pms-93183/
or just a car fast hydraulic and possibly tank folding bridges - but they also taught us to build classic wooden bridges on piles. In any case, I controlled and taught Russian transport-floating technology, namely PTS, GSP, https://www.pozary.cz/clanek/23760-obojzivelny-transporter-pts-10-uveze-po-vode-deset-tun-ve-vybave-nechybi-silny-navijak/ - This is the civilian version
But my entire military life, apart from the conclusion, I devoted myself to explosives - explosive traps, etc.
my company - bridging the Dije river after training within 30 minutes. I've also been on the Danube - of course it's more complicated - but it was bridged by Makus Aurelius and it's on a coin.
On my Saturday off for military training, my wife sent me to the store to stand in the long-endless even outside in the rain-lines of people waiting for meat- it was a socialist tradition that nothing useful was available - yes, there was bread, rolls, butter, milk, but you could find beef tenderloin, pork belly in the fall and in February they didn't have pigs -none, as my father humorously said that this is a new special communist variety - the kind that behaves and has no belly at all. ( Bananas, oranges, tangerines just before Christmas and after winning the battle in the store)
So I spent wonderful Saturdays in this butcher shop and heard the state butcher cut - weigh and sell
There were no private individuals and one of the important traditions even today, in my opinion, would need to be introduced - that there was an obligation to work - anyone who did not have a job was prosecuted for ( paragraph - a pest that feeds on others)and punished by prison. The employer put the stamp "Employed" on the identity card or the student - who did not have one and was legitimized by the police, was detained and placed in custody.
This butcher in a meat shop was throwing sliced meat on a scale
here he was throwing meat and the hand on the scale was jumping back and forth and back and forth from 20 to 80 and back and the butcher was shouting to the whole shop 46.50,-,,Forty six fifty.
And when he saw an acquaintance or someone he had a relationship with, they went to another room or he just bent down under the counter and pulled out the already wrapped meat that he had prepared.
State security has counted his financial income many times-every time it was reported that he bought a villa or a mountain hut and above all people did not tolerate him regularly buying a new car from the "Tuzex" store https://www.google.com/search?q=Tuzex&tbm=isch&ved=2ahUKEwi-qYXtg6-CAxUgnCcCHfnkDTcQ2-
https://cs.wikipedia.org/wiki/Tuzex

Bottom line: my father explained it to me, when someone in the city or the region and beyond won the lottery - a sports ticket or a winning ticket, it spread around the neighborhood - what a lucky person he is.
Well, this butcher immediately ran after the winner even before the named person took the prize and he bought a lottery ticket and a winning voucher and paid 30 percent extra -in addition, he gave to the original owner and under the cover of darkness he became the new holder of the winning ticket.
And people said to each other, "But the butcher is lucky."
And the police were checking,, for what did you buy a new car in tuzex foreign fiat-miafiora ,,-submit to us your income as an employee of the fatty industry trade approx. CZK 1,500???
Answer: Well, Comrades from the Police, I had great recurring great luck again in the lottery - (lotto) and I won 200,000Kčs
However, turning it into vouchers for shopping at Tuzex is impossible, and that's another story.
Even in this way, you could live happily or spend the whole day in the store for 1 kg of meat for 30 crowns.
