Revenues were needed to pay fees connected to transfers of land and property.
The first series came out in 1889, and they were British key types portraying Queen Victoria with the inscription ISLE OF MAN in the bottom tablet.
From 1894 some stamps were surcharged with the same face value in black in order to make the denomination easier to see.
[1] Unlike the keytypes, the 1966–76 issues were sold to collectors in presentation packs or as singles in mint condition, and therefore unused stamps are more commonly found.
