Were they not a concoction primarily for the tourists
In 1882, I don't think the island held much of a tourist interest, but when Walter George Quensell arrived in 1928, he saw and exploited the philatelic aspect of tin can mail.. I would surmise that until 1928 when Quensell saw the $$$ side, the mail was not nicknamed "tin can mail". In other words, I think that one would need to differentiate between tin cans used to get the mail to the ships prior to 1928 with the exploitation of tin can mail after 1928.
Here is a web site for tin can mail.
