I found the following Lincoln wheat cents while roll hunting the past few days. Are there any premium values to any of these: 1. 1928 d 2. 1947 no mint mark 3. 1955 d 4. 1957 d Any insight/advice on any of these is greatly appreciated! Thanks.
None of those jump out at me as key dates. Have a look at mintage figures; that's a good place to start. https://en.wikipedia.org/wiki/Lincoln_cent_mintage_figures Or Google for "Lincoln cent key dates".
