Sorry but your two Pennies are worth 1 Cent each.. First one looks like dried adhesive on the surface. The Second one is damaged.
Just because a coin is old does not mean it has value over and above the face value. In numismatics, condition is the major factor. ~ Chris
There are two values, personal and monetary. Monetary is nice, if you can afford it or just looking to make money. For me its a hobby, others its an investment. So, judge your coins for what they mean to you and continue to ask questions to learn.
How does one find an honest Coin shop? I hear stories of bringing in a collection and a rare coin will be replaced with a common one etc.
