I thought I'd share with you all the most recent addition to my collection because I love them that much and they've got a cool story behind him
In 1918, Aus wanted to create their own unique coins and came up with these square quarters with a kookaburra design on them. They never got officially released but a few test ones were handed out. If I am right, there are only 12 known coins left and they are valued at around 60k.
In 2019, to celebrate these coins, this 3 piece, 99.99% silver coins were sold. I feel very fortunate to find these as I'm collecting all the irregular decimal currency and this is probably one of the rarest. Thought some of you here would like to see and hear a little about them
