No. None are RPMs with the exception of possibly the 56D and the 57D (the non-plated one). EDIT: 56D : http://coppercoins.com/lincoln/diestate.php?date=1956&die_id=1956d1mm001&die_state=mds 57D: http://coppercoins.com/lincoln/diestate.php?date=1957&die_id=1957d1mm002&die_state=eds
What about the 1957D steel penny, should be on a copper planchet and the 1986D and the 2005P dbl mint mark?
IMO none of them are worth much. If the true RPM's were in better condition they probably would have some value. The 57-D not a steel cent. Probably plated. Look at the copper color around the edge. In 2005 the mint mark was not hand punched onto the die; IMO it's MD. Here's a listing of the 1986 D RPM's http://varietyvista.com/02b LC RPMs Vol 2/RPMs 1986D.htm Doesn't look like any of those listed. Need a better photo of the mint mark.
You can research your 56-D & 57-D RPM's on these sites: http://doubleddie.com/307764.html http://varietyvista.com/ http://lincolncentresource.com/ There's more if you need them.
I have placed a magnet to the 1957 steel penny and it acts like my 1943 steel so some one did a great job counterfeiting. Thanks for info
