This is the first of a series of posts describing the imperforated pairs of the late XIX and early XX century.
This time, we have an incredible vertical pair imperforated in between of the 20 Cts from the 1901 issue.
It´s being said that this error happened between 2 rows only. So, this means that only 10 of these happened.
Now, do you think that errors that only 10 exist are worth $1.000? Of course not! In my opinion the Scott catalog is under rating many Costa Rican stamps. A great example are the imperforated pairs from the late 1800’s through the early 1900’s. Fortunately, the market is taking action and setting the right prices.
