1971-S 1C DDO or MD?

Howdy,
I can't match this 1971-s up with any of the examples on Wexler's and wondering if there is one that indicates a die crack running through the letter W in WE or if this is MD?
Thanks again

I think it's worthless doubling but not sure mint mark looks like an rmp unless it is a true doubled die.

 

i see a die crack running from the ear to the w in we

 

I'm sorry my discription was not specific about the length and I need to work on that.

 

It appears to be MD. Mint marks were hand punched in the working dies until 1989.

 

It's strike doubling. It's in nice shape, though, and an S, so sock it away.

 

Md to me.

 

MD, a true double die should add to the width/thickness of a device, when both portion are together. MD will have both parts add together and be almost exact same thickness of a normal. IMO, Jim
