ANSWER: It’s shocking, I know, but the Honorable Justo Rufino Barrios has clearly been (c) bisected. Authorized bisects usually paid for postage at half the face value of the complete stamp. The problem is identifying a legitimate bisect, and so the collector is one safest ground if the bisect is on a cover or tied to a postmark. This Guatemalan bisect (Scott 300) is easily identified by its diagonal perforation of 11 1/2. The original stamp (Scott 235), shown here, was issued in 1929, the bisect in 1941. Señor Barrios was Guatemalan president from 1873- 1885.
