Hi Blinky,
Its great isn't it when you finally pull something of worth (apart from the usual nails, slugs etc etc) out of the ground and wonder where it came from and who held it last. Recently, while at Maldon in Vic. I had a swing in the bush behind the caravan park. I must confess I really wasn't expecting anything but as I wondered back to the park after walking up a decent hill, I happened on a 1911 King George penny, just laying there in the sun. If it was dropped prior to but around the time the pre-decimals were fazed out, its been sun baking for 46 YEARS.
Since then I added to the unusual finds. A 1947 Florin, and 2 half pennies, on the banks of the river at Echuca. A Chinese coin and a Four penny weight at Ararat. But none of the yellow stuff yet. But I live in hope!
And I wondered who'd dropped it.
