@TAB my partner's dad use to have a big jar that he was filling up with the round 50c pieces. And my partner said that he and his brother used to steal coins out of the jar and spend them. Lol
His mum still has the jar and it she must still have some, as she sent me one so I could add it to my 50c folder.
I have started looking at coin auctions and they seem to sell a heap on there.
I do vaguely remember about people adding coins to puddings at Christmas time. I remember mum telling me that she cracked a tooth when she bit the coin. You can still purchase the coins. I just found these on Downies Collectables. Mind you they costs $59.95. So not cheap.

My cousin who used to collect coins, died 23 years ago, and my mum said that there was a big bag of coins amongst his possessions. But since hordes everything, she has no idea where they are. I suppose I will find them, once my mum passes and I have to wonderful job of trying to empty her house which is full of things she hasn't used in over 10 years. Not looking forward to that. But there could be some hidden treasures in there.
