    Thanks - I hope they are helpful to the CoinTalk community. Anything that doesn't look correct let me know. Some of the images I mapped from weren't the best. Sorry for continuing to bump this thread but I can only work on this in blocks of time - compiling several CAD files into one orderly CAD file to convert into a jpg file takes me a little time. Not because it is that difficult of a process. It is because - as it turns out - I have learned I am a very sloppy file manager that becomes befuddled fairly easy.

    Now for the 1937 Lincoln Cent.
    Is the RPM cross reference proving useful? If you see any errors in the x-ref feel free to post corrections in this thread.

    It sounds as if you're describing me to a T. "Brothers of different mothers"! I still prefer XP to the newer software where peripherals weren't considered of virtually any importance. There's virtually no backwards compatibility, printers can't be properly interfaced by the manufacturer to the O.S. which isn't supported any longer (as if it ever was). In my opinion, unless your into "streaming", etc. the newer systems designed for multitasking, but not fully capable, can hardly accomplish anything completely other than social tasking.

    My spreadsheets, etc. are still in Lotus and Quattro type formats where data from complex formulas were interlinked between hundreds of spreadsheets, updated by a stroke. Open-Office could read and convert messaging from the multiple Microsoft languages which were version and "package sensitive", unable to be read by "up-dates". Up-grade from FAT32 to NTFS in XP various O.S. "packages" really created a mess, unable to be read by a new version of the same O.S.. I still use many older systems that were task oriented, just can no longer print my results. Regardless, I've purchased new printers hoping to print pages generated in WIN7, 8, 10, Vista32, Vista64, and been told by printer manufactures technicians that only Microsoft personnel can assist. LOL

    You've done a great task in helping individuals who are in the normal formative process of U.S. coin collecting.

    Your efforts are greatly appreciated.

    What are you using for a "browser" in XP, as I.E., Chrome, Firefox, Microsoft, Google, Mozilla, etc. will intentionally destroy/disable the O.S. if updates are allowed?

    I also have an XP system which runs some software that won't run on a newer platform without purchasing the newer version. I still run those programs occasionally but the XP system is NEVER connected to the internet. Too many security risks.

    I also appreciate the time and effort that justafarmer has put into this project and especially sharing it freely.

    If you look at the 1941-D RPM Cross Reference - you'll see that Wexler (WRPM) has crossed referenced to all CONECA (RPM). Coppercoins (1MM) has cross referenced to all CONECA except RPM-009. Coppercoins (1MM) has four dies that have not been cross referenced to either CONECA (RPM) or Wexler (WRPM) being 1MM-009, 1MM-010, 1MM-011 and 1MM-012.

    I only have maps for 1MM-010, 1MM-011 and 1MM-012. You can look at these maps and compare them to the map of RPM-009 and esily recognize that 1MM-010, 1MM-011 and 1MM-012 do not match RPM-009. Especially if you use the provided gridlines that gives a visual reference for the mint mark location for each variety. But I did an overlay anyway.

    Now that it has been determined that 1MM-010, 1MM-011 or 1MM-012 are not possible matches for cross reference to RPM-009. I did the same for the un-cross referenced 1941-D WRPMs.

    Sorry -looks like I made an error on the 1942-S Lincoln Cents. The first map labeled RPM-014 should be labeled RPM-013. Corrected image is below.
