thanks for clearing that up paulmarr.
Now that i think about it i did put some good condition 3 pence in yesterday and it came up mint with no damage.
So i imagine this spot, where i found 2x 6 pence yesterday, pennys and the 3 pence today all had similar wear, because it was in the open for 70 years with no tree cover.
I havent done any park hunting yet. Mostly bush hunting where no one has been yet. But yes if they were in the park they would be in similar condition due to the exposure and no shade, the coins i found in the bush with not much sunlight were in beautiful shape.
Hoping to find more of them suckas.
Im deciding on getting a new detector.
After find the 3 pence today i dropped the coin on the ground and hovered over in to realist it only picks up the small coin 5-6 inches on full sensitivity. LArger objects are different. But wanting a good detector that doesnt blow the budget that can go say 10 inches on a 3 pence. And can be used near salt water low tide, any tips?
