Among my Grandpa's coin collection passed down to me was this 1915 Cuban Veinte Centavos. After doing a little research I found that there were two varieties of this coin, a course reeded version and a fine reeded version. So, I marked the northern point on the star and marked the reed directly north of that and started counting. Some reeds were easy to see and others showed were the indentions of the gaps are and I counted 146 reeds all the way around. Although worn I am glad to add this to the collection.
