Same in NZ, our coin pusher machines got banned in the 1980s, after several had been tampered with (Coins went down the chute, but did not come into the tray - mirrors made it look like they did but disappeared into a secret box under the machine).
I am still quite young, but maybe an older Kiwi may remember them - I remember they were mostly 2 cent coins.
All we have are those horrible claw machines and they are rigged, most dispense knockoff fluffy junk - pokemons and Japanese cutesy pie character things and fake looking iphones (Well they did, have not been to an arcade since mid 2010s).
Pokies suck up $2 coins, but since 2018 most have been converted to notes or vouchers only and pay out in vouchers, I haven't played one since 2019 and all the pubs have been closed since August, so it may have changed now. I think that sucks, part of the joy I had in the days of my addiqtion was the sound of metal filling a tray and the ca ching, ching noises.
NumisRob seems your gamble paid off though.
Loving Halfcrowns. British and Commonwealth coins 1750 - 1950 and anything Kiwi.
If it's round, shiny and silvery I will love it.
