So I saw the picture online of the 1961 D over horizontal D Lincoln Cent. And then, I found one! So cool! But then something even more amazing happened after that. I found a 1963 D over horizontal D except the D is upside down with the straight edge facing south! I looked online and could not find even one. Does that mean it is the only one? I will post the pictures next.
These were taken with my microscope. Trying to use my digital camera for the full coin shots but they are still blurry. Don't have a cell phone. I will try to use the automatic delayed picture for the camera if it has one.
The following sites have comprehensive listings of RPMs. Look for an EXACT match. If "it's close", you don't have it. Bookmark them for use if you think you found a doubled die www.doubleddie.com Www.varietyvista.com
A horizontal mint mark should be the very same size, height and width, as the vertical mint mark, just rotated. I do not see such on these. Yes, some deformation due to hits, but nothing confirming a rotation. Sorry . IMO, Jim
The confirmed ones I saw online were not that way. Some of them were very faint under the bold MM. If you look closely at the 1961 D microscope picture you can clearly see a faint D facing to the south. The bottom part of the D is protruding out the left side of the bold D and crossing the center of it. The 1963 D picture has a bolder D with the curve going through the middle of the bold D and the straight line on the D protruding south of the bold D. Thank you for your opinion though.
@Coppertop Welcome to CT. You can also look through the listings in Brian's Variety Coins. Over 75 RPMs are listed for your 1961 D cent. Brian's Variety Coins - 1961 One Cent Repunched Mintmarks (briansvarietycoins.com) @Oldhoopster and @desertgem gave you sound advice for finding your RPM. Happy hunting.
The mint Only used a limited number of mm punches and I believe only 1 D punch was used in the early 60s (I can't locate the reference, however). If you take the Time to learn the die making process, you'll understand why @desertgem told you the mm should be the same size and font. It can't be anything else. He wasn't giving you an opinion, he was telling you facts that he knows from decades of collecting
The 63D cent you showed cannot be the same as the FS501 D/D/D Others have eluded to the fact that MM were hand punched into the working die until 1989. A coin made with a set of dies for 1961 will not have the same die markers as one made with a set of dies used for 1963. One other way to confirm a RPM is the MM positioning. Lets use these two RPM's from 1962D In the links you will notice the position of the MM in relation to the date.

Sometimes these guys whose only talent is obsessing over and classifying these are seeing things. Another way to put that is, when the only tool you have is a hammer, every problem tends to look like a nail.
I stand corrected, after some more cleaning, it appears that all I have is two RPM's. Clutter was making it appear to be something else. Sorry. Learning.
Be careful about cleaning, if you do come across a good one improper cleaning can really hurt the value.
