Re: Let's see your best dug worn out coin!
1940 (s? d? plain?) wheatie, found outside of a culvert on the beach. It had probably been subjected to seawater for decades. I seem to be lucky with really distressed coins as I can still usually read the dataes. Maybe also thanks to being severely nearsighted, so when I take off my glasses I pretty much can see to the molecular level!
Edit: I really love this coin because it's so bright red. Despite the lower value of non-silver or otherwise cheaper metal coins including copper, some of my post '64 coins are my favorites as their patinas are so bizarre. Purple, blue, green, pink...and I love finding pennies under old trees as the roots or leaves/needles or something tends to make them bright red.
