Mexico 20c 1955 - Pyramid of the Sun

One of the key dates of the series that features the old & smaller style eagle. Be sure the check out the key date of the later series. I'm not sure the mintage is known for sure, KM shows a healthy issue but the new design (which was introduced in 1955) with larger eagle is included in the figures. A striking design with apparent high relief on the Pyramid of the Sun using perspective. Highest graded on PCGS as MS66+ you can see their site photo of this specimen at this https://images.pcgs.com/CoinFacts/37311338_167786810_max.jpg
