I started collecting stamps when we got mail. Back in the day, before you were born, people used to send letters with stamps on. There were some really nice ones of different birds, fish or animals. Many of the stamps had Queen Elizabeth 2 on them. I started collecting the bird and animal stamps because they interested me. People found out I collected stamps and they would send letters to someone in the family but use a variety of cheaper stamps to pay for the letter.
eg: Letters cost 30cents to deliver so instead of putting a 30cent stamp on the envelope, they might put 6 x 5cent stamps on it.
Stamp collecting was quite common last century because there wasn't a lot of things to collect and stamps were cheap and quite often colourful, so a lot of people collected them. They didn't necessarily show them or go to stamp clubs but a lot of people had an old tin or box with various stamps in. Over time when people died they passed their stamp collections onto me or mum & dad, and I ended up with them.
As I collected more stamps I started looking for fish and bird stamps and they weren't that common. Sometimes the postal companies around the world did fish, bird or plant stamps and I would get them. At one of the ANGFA WA meetings we had a few fish stamps appear on the auction table and there was a bidding was between me and Ken Shaw (RIP Ken). We were bidding over a stamp with an Iriatherina werneri on it and Ken was meant to be running the auction but every time I bid, he bid higher just to drive the price up. Eventually I got up and went over to him and said stop it. He didn't and we kept bidding for a bit. Eventually I won. Straight after that he pulls out another stamp that was exactly the same and the bidding war was on again. It was fun
but I miss Ken, he was a nice guy.

As for coins, I started collecting them when I was little (5 or 6 years old). Dad came back from overseas and brought some overseas currency with him to give to us kids. I was fascinated by the coins made overseas. They were similar but different. Then I got a silver 50 cent coin from my grandmother and that really got me collecting. I used to look for $1 and $2 notes that were in perfect condition and kept them. Then I started getting the other notes ($5, 10, 20, 50) and started to notice different $1 and $2 notes had different people on them. I looked into them and they had different people on different notes.
We started off with paper notes and then went to the first plastic notes. The blue on the early plastic $10 note was stunning when new. Around the time they went to plastic notes they dropped $1 and $2 notes and replaced them with gold coins (they aren't actually gold they just look gold). Plastic notes were great because they didn't fall apart if you left your wallet in your pants when it got washed. The old paper notes didn't hold up too well to spending an hour in the washing machine.
