2 ungraded used singles of the 2d - 6d dull lilac mauve - light ultramarine Queen Victoria from the 1870-1884 Queen Victoria Keyplate Issue, #1 barred numeral cancel for Melmourne, August 2nd 1871 Ballorat CDS.
Both stamps are faulty, but the cancellations are interesting.
Gibbons doesn't list these varieties, so we estimate them at $2.
