1914-D 1942/1

I cant say "should/shouldnt" -- if you were me you would get both graded if they were at or above AG condition. My resources tell me the value of your coins in "Fine" condition are:

1914-D Cent
PCGS: $410
Numismedia: $402

1942/1 Dime
PCGS: $650
Numismedia: $600

There are several grading companies.

PCGS -- http://pcgs.com/
NGC -- http://www.ngccoin.com/
ANACs -- http://anacs.com/
IGC -- http://www.icgcoin.com/

I defer to other experts' input and opinion who is best, most appropriate for your needs.

Copper, I understand your sentiments about cleaned; however, there are lots of collectors who'll buy cleaned VG+ key dates and pay nearly 85% of uncleaned value for them.

Unless your planning on selling them, why bother having them graded. You will only have a large hunk of plastic. If what you say is that you've had them for a long, long time, why have them slabbed now. You can find out if they are faked by starting looking up the 14D Cent on the https://www.coppercoins.com web site. The Mercury dime is rather a difficult one to fake anyway and not real popular way, way back in the good old days. Actually many of the first Whitman Folders and Albums did not have those in there. You should try looking up the 14D cent though. As kids way, way back we used to have fun with electric erasers making 44D's look like 14D's. We erased the D off the 1922's also to make 1922 Plain Lincoln Cents. We did lots of stupid things but then that is a kid for you.
I am not a big fan of slabbed coins. Every one I have ever purchased has been broken out and placed in an Album. I just don't like a pile of plastic instead of a coin collection.

I would have these graded just to establish they are genuine. I would use ANACS since they will slab even "problem" coins with cleaning or damage, as long as they are genuine. If you later choose to break them out to put in an album, just keep the slab inserts. They will help confirm authenticity to any prospective buyers if and when you want to sell.

I can blow it up but it want be clear! If you tell me how to clear it up I will do it

For me, simple answer, simple rule for key dates: keep it raw, sell it slabbed.

Got you covered amac

I have a 1914 D that was graded XF40 by USCG. Yours looks close, a little more wear in the hair and wheat stalks, but I'm by no means an expert. I paid $325 for mine. the 1942/1 I can't realy see the overdate in your pics, and I don't have one (yet), but as others have said, if your thinking of selling, slab, my opinion.
