This listing is for a 1939-B 5 Mk Reichsmark Hindenburg silver coin, in mint condition, graded MS63 by PCGS.  

These coins were made with 90% silver content. 

This is the last year that 5 reichsmark coins were produced as they stopped being made with the outbreak of WW2. 

This coin was minted in Vienna, which is a very interesting mintage, as this was the first (and only) year that these 5 reichsmark coins were produced there. As such this is a highly desirable and unique year/mintmark.
