Philippines 20 Centavos 1944 D/S

I just got some coins and I am not sure if I have a D/S coin

Picture 1 is a D



Is picture 2 a D/S ?

I have the exact same date and since there wasn't any more options, I supposed that I just marked it as the 1944 one! So I guess so  

The D/S is a D mintmark over the S mintmark.  

In another forum I have that there should be 2 lines. 1 for D  and 1 for D/S

I was not aware of this. My coin is just like yours! Do any other swappers have any info on this?

 "The 1944 and 1945 Commonwealth of the Philippines coinage contain several interesting Die Varieties. There is a 1944 D/S (D over S Mint Mark) Allen Catalog Number 12.04a. The 1944 D over S Twenty Centavos is unique among USA/Philippine Die Varities in that it is the only time during the 43 year history of U.S./Philippine coinage that a mint mark was ever over-punched with the mint mark from a different mint. The 6th edition of the Allen Catalog lists a combined (NGC, PCGS, ANACS) certified population for this important die variety in MS66 as 12 coins with only 4 specimens graded higher. The NGC population for this coin in MS66 is 6 coins with only 4 specimens graded higher."
  There is one for sale at $390 described as "The under image is pleasantly clear with the top of the “S” peeping out on top of the “D” and you can clearly see the “S” inside the “D”."

  I tried to find a close-up picture but they were all too far away and looked like a normal D to me.
