Okay - so I've searched through several thousand pennies now and I think I have something. I'd appreciate an expert opinion! I believe this to be a 1936 DDO penny. Thanks in advance!
From here it sure looks like a winner! http://www.lincolncentresource.com/doubledies/1936doubledies.html http://www.varietyvista.com/01a LC Doubled Dies Vol 1/1936PDDO001.htm Unfortunately, it's not in the best condition. Nice find though!
