1937 50C Rectangles, (36), RD MS65RD Certification #49347062, PCGS #849157

Bought in a small coin shop in Bilbao, Spain. Quadrados, Squared or Rectangles.... Whatever you want to call the beads around the reverse design are a bit more elusive than the dot pattern. What is ever harder to find are these coins with legible dates struck into the stars on either side of the 1937 date. The actual date these coins were issued was 1934 and 1936 with the 3 and 6 being struck into the small stars on either side of the 1937 date. More often than not, these tiny numerals inside the stars did not strike up well with what I would say being the majority of this design not having an actual date other than the 1937 at the base. Additionally, I do not know why they struck these coins 3 years prior (1934) to the main emission date of 1937, and then again in 1936; the only 2 years these Copper 50 Centimos coins were struck? Usually, the principal date when Spanish coins are first struck coincides with the same date in one or two small stars with the date's digits. If anybody reading this knows the answer to this, please let me know!? And Yes, I realize this was in the middle of the Spanish Civil War so I would assume this had a lot to do with production issues??
