Have been finding a heap of coins in suburbia over the last few months but one local oval has given up a few that l never expected to find on it thinking its not old enough.
The first one was a Cartwheel penny 1797 and on the same day a George lll penny around 1806 and then a week or so later a George lll farthing around 1806 but the dates cant be read so purely speculation.
They arent worth much other than historical value but good finds none the less.
The cartwheel was at least 8to10https://www.prospectingaustralia.com/forum/img/member-images/17391/1600062395_e950c8b6-3e44-40e0-a9a0-2841a71669b5.jpg
Sounds like a good spot. Maybe the oval has had dirt brought in over the years and that's how the coins arrived there. I found my first cartwheel at a sportsfield near Curl Curl, that area was nowhere near old enough and it's a reclaimed landfill, I reckon the coin came from elsewhere as there was no possibility that it was lost there originally.
2nd one I found was a park in Western Sydney, that was in hard packed clay about 15cm down and in pretty good condition, I don't reckon it had moved far from where it was dropped.
Anyway hopefully the site keeps producing the goods.
