Question
I have a 1942 Liberty Half Dollar that has written on the coin cover 1942 D/S.  I looked on the coin and it does look like the mint mark has a D with an S in it. Is that possible? I've tried to do some research but haven't found anything. I hope you can help. Thanks!!!!!

Answer
Hello Susan,                                                 

These are called Re-punched mint marks, or RPM's for short.
I did not find a D over S in my catalogs for the 1942 Half Dollar. But this does not mean that it is not possible,  just that (if it is authentic) it does not have enough popularity among collectors or enough sales information to merit a pricing entry.
I only found reports of  D over D and  S over S mint marks repunched into the dies.

If you want an experienced coin person to look at the coin write me back, give me the nearest large Cities, some postal zip codes and telephone area codes. I will refer you to an expert in your area.

I also want to mention COMBINED ORGANIZATION of NUMISMATIC ERROR COLLECTORS ASSOCIATION, they are the ultimate experts in the error coin field.  
CONECA is a national numismatic organization devoted to the education of error and variety coin collectors. CONECA focuses on many error and variety specialties, including doubled dies, Re-punched mint marks, multiple errors, clips, double strikes, off-metals and off-centers just to name a few.

Please feel free to ask me others about this or any US Coin. If there any more information you require on this question just ask.

Thank You and Good Luck
