| The first coil stamps of the world 1 Dinero rose printed in Lima in 1862 on horizontal strips of paper. |
| On cover, from HUANCAVELICA to LIMA, double rate certified, April 12, 1867 Notice a total of 8 star postmarks [3 on each lateral side plus 2, one on the upper and lower middle], this practice was used to indicate the "certification status" of the mail during handling, additionally a second "Certification" mark emphasises the status of this letter. The CDS cancel indicates the day the letter was certified, and to cancel the stamps, a circle dot matrix marking with the town name in the middle was used to cancel the 7 stamps. Quite elaborated job to highlight the certification status. |
