1919 Lincoln, and then there is this other coin...size of a nickel...color of a penny. I'll give my thoughts and see how close I am to the experts: 1919: G-4; maybe $0.10-$0.20. I have absolutely no idea on the "?ERROR?".
Hard to tell by the pics but it appears to be the Lincoln memorial running vertically is why I thought penny and nickel were combined somehow.
it looks like the reverse of the 2nd coin has something imbedded it it's surface. Post Mint Damage would be guess.
