Finding a postcard with mixed franking from the 1901-1907 issues is not that easy.
A common practice for Costa Rica stamps during the late 1800’s and the early 1900’s was to demonetize issues as soon as the following was allowed to circulate.
In October 15th, 1907 the 1901 issue was demonetized to give its place to the 1907 issue. Everything seemed normal…until there was a shortage of the 1 céntimo stamp from the 1907 issue. As a temporary solution the government decided to make the 1 céntimo from the 1901 issue valid again.
According to my good friend Alvaro Castro Harrigan: there were two values from the 1901 issue that were valid to circulate along the 1907 issue, the 1 and 5 céntimos. The 5 céntimos was allowed to circulate only during a short time in 1908. Meanwhile, the 1 céntimo was allowed to circulate indefinitely until 1910.
The latest postcard with mixed franking from the 1901-1907 issues that I had seen was from February 1909…until now. I was able to find a beautiful postcard sent from Puntarenas to the United States during January 1910. The postcard has one 1 céntimo from the 1901 issue and two 2 céntimos stamps from the 1907 issue. Before parting to the United States, the postcard went to San Jose as usual.
