Hello guys. The first thing I want to know is your opinion about the grade for this coin. I'm new to coin collecting and grading my coins is really hard. I'm posting a picture here and a link to a high resolution picture too. Here is the high resolution picture -> http://www.drk.com.ar/images/1931_20c_arg.jpg
GOOD or perhaps VERY GOOD but no higher. There is too much detail lost due to wear. It is the lowest mintage coin for the KM 36 design that ran from 1905 to 1942 at 315,000.
Thank you very much! I hope I will learn coin grading by hearing others opinions. It is worth to notice the darkened top of the coin. It's due to a shadow while taking the picture.
