Nauru #58-71 1c-$1 1966-1968 Decimal Definitive Issue, Complete F-VF NH Set
A complete F-VF NH set of the 1966-1968 decimal definitive issue, all printed on different papers, showing varying degrees of fluorescence, ranging from dead to hibrite. In addition, the engraved stamps are all printed on Helecon paper, as noted below.
These stamps were printed by the Reserve Bank of Australia and thus will mirror Australian issues of the period, in terms of the varieties that exist. Most of the engraved stamps are found on dull paper, but starting in 1965, many of the Australian issues can be found on fluorescent paper. The photogravure issues are usually all fluorescent from the front, but on the back the fluorescence ranges from dull to hibrite. It is not known which varieties exist, or do not exist on this issue, but the picture taken under UV shows what is included with this lot.
The Australian equivalent of tagging is called Helecon, which is a chemical in the zinc sulphide group that fluoresces orange-red under long-wave UV light. The very first stamp to be issued with Helecon coating applied to the paper was the 11d Rabbit Bandicoot from the 1958-1964 definitive issue. Later, the 5d orange-red Queen Elizabeth II stamp from the 1963-1966 issue was issued with the Helecon incorporated into the ink. By the end of 1965 all stamps issued had Helecon applied to the paper. On this issue, most stamps are found with the paper coated with Helecon, so that they glow a dull orange-red.
