In my youth, I had the habit of smoking marijuana. Often we would all smoke in groups bring the cost of entry down while at the same time enjoying the company of friends. On more than one occasion I found myself alone and without the means to purchase the habit, I had begun to grow accustomed to. So being young I looked at my teenage worldly possession and would inquire about a trade. At times I found success other times I was met with the coincidence of wants. Sometimes I was able to overcome this by supply something says a video game, clothing, etc by trading something with a street price value of 2-3x the quantity I was looking to buy. Looking back I always knew it wasn’t a fair exchange in terms of value for dollar spent, but I understood that, I also overstood this was the key to overcoming to the coincidence of wants as it applied to smoking a few blunts of marijuana. Because the intrinsic value of items I would trade had the purchasing power to acquire 2-3x the quantity I would barter for in those scenarios. Thankfully that is in the past.
I recently bartered farm produce for fireplace wood, it was worth the exchange as I wanted to have the fireplace on

During high school Pogs and football (soccer) stickers were all the rage, I would often trade duplicates or unwanted ones (often in quantity) for sought after versions. It wasn’t unheard of for me to spend a weeks lunch money on purchasing new ones, without my Mothers knowledge!
When I was a kid my I had Pokemon Ruby and my friend had Pokemon Sapphire. He traded me his Serviper for my Zangoose.
I think that this was a very fair trade because each was exclusive to their respective games. Trading was the only way to acquire the pokemon we wanted and we both could easily catch a replacement of the pokemon that we were trading away.
A very primitive example.
Back in second grade, me and a friend of mine, back in the 2nd grade, were very enthusiastic about trading cards. We decided to trade some cards. He had offered several common cards in exchange for one of my (very) rare cards. Looking back, it is very hard to forgive him for taking advantage of my naive and primitive concept of value. It was definitely not a fair exchange and I have learned my lesson about rare commodities. 
Sister Takes Advantage
Before I knew about money, I would trade my shiny coins with my sister for her copper coins. Sure it was fair. I was trading 1 shiny coin for 1 copper coin. Pretty even ;-)When I was a kid I traded all the snow in my yard to my friend that lived next door for a stick that was wrapped in rope.
Oh wow this is interesting have to go back 50 years in time for this question and I actually remember it as i traded my hockey net and my hockey stick for a bicycle. At the time I think I got a great deal but when I want to play hockey of course well I thought I got the bad end of the deal.
- A barter transaction I’ve been apart of as child would be to trade a piece of my gum in exchange for a few of my friend’s chips.
Item 1: 1 piece of Gum
Item 2: 3 chips
Looking back this is a fair transaction because we both perceived them as equal value. I was craving the chips and he was craving the gum so we were both satisfied with the exchange. The piece of gum costs 5 cents and the entire bag of chips was 1 dollar so it made sense to us.
I remember collecting decorative napkins when I was around 10. I would trade few napkins just to get one that would match my 3-napkin-sets. 
As a child I traded many Yugioh cards, one particular trade was for a Buster Blader card to which I traded an extra Dark Magician I had. Looking back the trade was fair because I got the card I wanted and traded a card I had a copy of, the person I traded with also got a card they wanted however I don’t think they had another Buster Blader.

My father and I used to barter all the time growing up, he used to offer me to not shove his foot up my arse in exchange for me doing my chores. The items exchanged, fear and hard labor. Do I feel it was a fair exchange, not at all but that was also one of the lessons he was teaching at the same time which is that life is not fair.
At school, during lunch breaks, I exchanged my full 35cl bottle of Coca-Cola for some black currant juice at 35cl fill.
I think it was a good deal, because at the time I wanted black currant juice, and my partner wanted coke

I used to trade stamps as a kid with other kids. Value of stamps was based on scarcity of the different stamps, countries they were from as well as aesthetics and personal preference :).
I guess whenever Me and my friends go out drinking and eah one pays for one round is some sort of barter as sometimes we get different drinks or someone pays an extra one or less than in the previous round. It is fair because we agree to it, but it isn’t precise.
