I am not sure if I have that worded correctly, but was wondering how to tell a true DDO? I can't get a clear enough picture with my phone and loupe, but I have a 1968d penny and on the date as well as on the D there is a slight outline tracing them.. I have read through a few posts and looked at some of the pictures and am not sure how to fully tell. I wish I would have been able to get a clear picture of it, but neither loupe nor phone would cooperate.. I hope without a picture you are able to answer my question, if not I will have to do a bit more research and try and figure it out. It is so slight it may not even matter anyways. Thank you!

Keyword Wexler's Die Varieties and you should find what you are looking for and how to distinguish a double die from what appears to be one. I was having the same problem yesterday with what appeared to be a 1955-S DDR but unfortunately it turned out to be a 1955-S MDR machine damage reverse.

Thank you.. I've been reading a lot of this site, but apparently haven't ran across that yet.. I am finding so much great info and pictures.. It's often frustrating trying to decipher damage to mint error..

A good example of a MD vs DDO or DDR is my post from yesterday. The 1955-S Lincoln Cent DDR. There are some photos there to look at and comments from the experts. They are very informative.

Keep in mind that the MD can show in any direction from coin to coin. It doesn't always look the same on all coins struck in that run:

Note the different areas affect from strike to strike? (note the die scratch SE-NW between the 1 & 9? That shows that all these examples were from the same run for that die pair.

interesting. I have yet to find a roll with all the same coins though.. a month ago I knew nothing about pennies other than they spend 1c. Today I know more than I thought there was to know.. Its actually addicting to learn so much on something like this.. :)

This is an old picture of Coop's, but it is to the point and should help you a lot.


There are other forms of worthless doubling and valuable doubling, but this is a good starting foundation for you.
