Here is a penny I got as change, it's a 1941 wheat penny, I couldn't believe I finally found ANY wheat penny.
I am quite interested in a mark under the word 'Trust' on the head side of the coin, it looks like a stylish D of some sort.
I gently removed some green junk off of the coin which I presume was a type of rust and it looks OK now, the penny is rather dark red or brown in color and in relatively good condition.
Is it worth anything? or should I not even bother selling it on Ebay and keep it for my self?
Thanks!
