Isn't my 73D Cent lovely?

[KarenHolcomb]

Ok, with a find that is actually discussed and pictured in Sullivans Error-Ref.com I couldn't possibly stay away from my favorite forum any longer. That said, this Memorial Cent also has several other possible errors that I would like to have looked at and either confirmed or disproved. I think it is in fairly decent shape so if it demands  premium as a rare error please let me know-if it doesn't please let me know that too. And if so where should I post it or how do I get it graded and attritioned? As you all know by now I am poor and need that one good coin to really start getting into collecting something other than my pocket change. 

So. The 7 in the date? Doubled? Is that an interior crack going down through the top of Lincoln's head and then out the back to the edge at a NW angle? And the letters on of USOA seem to be about to fall off the coin. And finally in bay #6 by the left knee to the floor? That isn't already listed as a Double Die but it's definitely something. Any input y'all have is appreciated. Thanks and sorry I got all butthurt the other day and I hope it's ok that I returned.

I can't enlarge the pics enough to make out details without it getting blurry.

Ok. Idk how to make them bigger. I was lucky to get them to upload at all. Thanks for trying JB.
