There are two types of pennies for each of the ones mentioned in your question. One would have been minted in San Francisco and the other would have been minted in Denver. This is significant because the price differs in terms of where it was minted and the current condition it is in. The value of the 1916 Denver penny is 58c in good condition and $67.50 if it is uncirculated. The 1916 San Francisco penny is 85c in good condition and $93.00 uncirculated. The 1938 D is 5c in good condition and $3.75 uncirculated while the 1938 S is 5c in good condition and $2.75 uncirculated. Lastly, the 1946 D is 3c in good condition and 46c uncirculated whereas the San Francisco version is 4c in good condition and 46c uncirculated.
The majority of coin dealers will assess the pennies in various conditions and in finer detail. I identified how much the pennies in question would be worth if in good condition, however, dealers will have more categories including worse, good, fine and extremely fine. The difference between good and fine could be significantly larger or it could be minute. It goes without saying that dealers will be more interested in better quality coins because the majority of their clients will want the best conditions for their collection. Due to this it is important that you should get the coins checked out by a professional dealer to determine what the exact value of the penny is. You should think about consulting with the Professional Coin Grading Service (PCGS) or the Numismatic Guaranty Corporation (NGC) as they are the leading coin grading services available.
