Can anyone tell me anything about theses coins, got them from my father

For starters we would need to know what if any mintmarks are on the coins.  The  mintmarks would be located above the date.  There are three possibilities a D , an S, or no mintmark.

Thank you for relying, Looks like they all have the mint mark D, any information would be appreciated, :-)

[Conder101]

OK, since they have a D mintmark that means they are all made of copper nickel clad copper (S mintmarks would have had the possibility of being 40% silver).  The D mint coins were struck in large quantities and were released into circulation.  Unless they have absolutely no wear,  basically no contact marks and are well struck then they are common and worth between $1.25 and a couple dollars.  On the bright side a set of Ike is a fairly easy set to put together and unless you insist on the extremely high grade coins it isn't an expensive set either.

Conder101 has it exactly right.  There is very little interest in these if circulated
